REDUCING CONSUMPTION OF MELT BLOWN FIBER MANUFACTURING PROCESSES
Principle Investigator: Dr. Bill Klinzing Advanced Manufacturing LLC
National Lab Partner: Dr. Ian Foster, Dr. Sibendu Som, Dr. Debolina Dasgupta - Argonne National Laboratory
Summary:
This proposal aims at minimizing energy consumption of melt blown (MB) fiber manufacturing processes. Such processes are widely used for 3M products including filters, fabrics and insulation materials. The most impactful recent example is the base material for the making N95 mask during the COVID-19 pandemic. The process is extremely energy intensive since it relies heavily on compressed air and electrical heating. This proposal seeks methods to minimize energy consumption through a combination of High-Performance Computing, Computational Fluid Dynamics, and Machine Learning. It is estimated that the optimization will lead to a 20% reduction in energy consumption. Approximately 300 tons of MB nonwovens are produced worldwide each year by 3M and other manufacturers, consuming approximately 245 GW hour/year. A 20% (49 GW hour/year) reduction in energy consumption would have a global impact as 3M is a major player in the nonwoven manufacturing market and other manufacturers would likely follow suit.

Summary:
The objective of this project is to develop and manufacture cost-effective, oxide dispersion-strengthened (ODS), NiCrFeCo-rich high entropy alloys (HEAs) that are superior to Ni-based superalloys (e.g. IN740) for repair or replacement service in extreme environments. High throughput (HT), multiscale computer modeling will be performed to accelerate alloy discovery by interrogating the intrinsic properties of the alloys including phase stability, diffusion, stacking faults energy, short-range order, and yield strength. In particular, a hierarchical microstructure will be sought: A ductile high-entropy solid solution matrix in the face-centered cubic (FCC) structure that is strengthened by high-entropy coherent ordered L12 precipitates and nano oxides dispersion, and further toughened by transformation induced plasticity (TRIP) and/or twinning induced plasticity (TWIP) effects. Advanced Manufacturing LLC (AMLLC) and Connecticut Center of Advanced Technology (CCAT) will carry out validation and evaluation, including additive manufacturing (AM), microstructure characterization, mechanical properties test and oxidation experiments.

Principle Investigator: Dr. Yuri Plotnikov, Dr. Kaushik Joshi, Dr. Rich Martukanitz, Dr. Nasser Ghariban, Dr. Gaurav Ameta
National Lab Partner: Dr. Yousub Lee – Oak Ridge National Laboratory
Summary:
The proposed program is focused on establishing computational framework, foundational knowledge, and additive manufacturing (AM) capabilities for accelerating the use of refractory metals for gas turbine generators, which is considered a significant enabling technology for increasing operating temperatures and improving efficiency of these systems. The program will develop and apply high-fidelity process and material models for simulation of potential defects, deposition geometry, and resultant microstructure of refractory alloys produced using directed energy deposition (DED) AM. Upon validation of the developed model, virtual and physical experiments will be designed and conducted to create process and material maps. The maps will assist in establishing quantitative relationships to define the influence of primary processing parameters on attributes used to delineate process consistency and product quality for meeting the stringent requirements for this industry. The developed models will be used to conduct significant virtual experimentation at the supercomputing facilities within Oak Ridge National Laboratory.

IMPROVING MODELING AND SIMULATION TOOLS TO INDUCTION PIPE BENDING
Principle Investigator: Dr. John Shingledecker, Mr. Kavarana Firdosh
National Lab Partner: Dr. Noah Paulson , Argonne National Laboratory
Summary:
The proposed project seeks to leverage high performance computing (HPC) and active machine learning to apply state-of-the-art modeling and simulation tools to induction pipe bending of nickel-based alloys for energy applications. Induction bending offers significant improvements to the production of energy application piping systems, which enable highly efficient power cycles. However, the process has largely been ignored by the modeling community, and therefore the introduction of new piping alloys designed for high-temperature service require a trial-and-error experience-based approach. HPC offers the possibility of developing an accurate model of the non-symmetric 3-D temperature and strain profiles during heating, bending, cooling, and heat-treatment. Active machine learning can then efficiently construct an optimal surrogate model for the high-fidelity simulations, and therefore enable a large multi-variable assessment of the wide range of potential pipe sizes and process controls to develop scientifically sound approaches to enhance product quality and reduce overall energy intensity.

Principle Investigator: Dr. Karthik Nithyanandam
National Lab Partner: Dr. Zhiwen Ma, Dr. Michael Martin , National Energy Renewable Laboratory
Summary:
Industrial process heating (IPH) accounts for ~70% of US manufacturing energy use and is primarily produced by fossil fuel combustion. Approximately, 1500 TWht (~60%) of IPH demand is in the temperature range of 100-300℃. Industrial applications in this temperature range include drying, hydrothermal processing, thermal enhanced oil recovery, food and beverage, bioethanol production, etc. Cost-effective thermal energy storage (TES) that increases the utilization of waste and renewable heat (solar, geothermal, etc.) could provide significant energy savings and reliable heat sources, decrease emissions, and increase US manufacturing competitiveness through reductions in fuel consumption. This HPC4EI project will facilitate Element 16’s development and commercialization of low-cost and high-impact molten sulfur TES for dispatchable IPH and support its broad applications and deployment.

OPTIMIZING COUNTER CURRENCY AND IMPROVE SELECTIVE GAS PERMEATION
Principle Investigator: Mr. John Jensvold
National Lab Partner: Dr. Ramanan Sankaran , Oak Ridge National Laboratory
Summary:
Several gas separation applications such as the removal of CO2 from natural gas require a highly efficient gas separation membrane device to purify the feed stream with minimal loss of methane or other light hydrocarbons and a minimal loss of natural gas pressure. In both ways, energy loss as well as green-house gas emissions are minimized. This is often carried out with shell-side fed hollow fiber membrane modules equipped with membranes that can selectively permeate CO2 from the feed gas by means of a partial pressure driving force across the membrane. To maximize this driving force, the preferred module design is counter-current in which the permeate gas runs counter to the feed gas that is being processed. We propose to develop a CFD model that enables optimizing the counter-current flow patterns in the module while minimizing pressure drop. The CFD model will use effective media models informed by fiber resolved direct numerical simulations and will be validated against experimental flow measurements.

TRANSPORT ANALYSIS AND OPTIMIZATION IN A MW-SCALE CO2 ELECTROLYZER
Principle Investigator: Dr. Sichao, Twelve (formerly Opus 12)
National Lab Partner: Dr. Victor Beck , Lawrence Livermore National Laboratory
Summary:
Twelve (formerly Opus 12) is developing and scaling up a technology that converts CO2 into high-value chemicals and fuels using renewable electricity, which represents a significant opportunity to transform our global energy system, allowing society to utilize excess renewable energy and profitably utilize CO2 while closing the loop on greenhouse gas emissions. One important challenge relevant to scaling up is the need to manage heat generated at the electrodes to mitigate materials degradation and water management problems. Compared with exhaustive experimentations, High Performance Computing is a more viable and faster route to identify key fluid, thermal and reactive factors impacting scaled-up performance. Through this project, we seek to collaborate with LLNL to better understand the local thermal environment and its impact on water management in the MW-scale CO2 electrolyzers via developing a series of 3D electrolyzer cell and stack models, with the purpose of accelerating transformational technological advances in the industry.

HIGH PERFORMANCE AND REDUCED-COST MANUFACTURABILITY OF ELECTROCHROMIC (EC) DEVICES
Principle Investigator: Dr. Anoop Agrawal, Dr. John Cronin, Dr. Sahila Perananthan
National Lab Partner: Dr. Stephan Irle, Dr. Debsindhu Bhowmich, Dr. Dmitry Ganyushin , Oak Ridge National Laboratory
Summary:
The use of electrochromic (EC) dyes in Glass Dyenamic’s devices has shown to significantly reduce assembly cost for smart glass building windows with improved energy efficiency. Low manufacturing cost and aesthetic consideration has the potential of significantly increasing the adaptation of this technology in commercial and residential glass markets. However, the experimental design of suitable EC dyes with desired photophysical properties is highly resource intensive. We therefore propose a combined high-performance computing (HPC)- and machine learning (ML)-driven inverse structural design of anodic EC dyes based on high-level electronic structure theory to predict their photophysical properties in neutral and oxidized states. Highly accurate ab initio multireference wavefunction methods will be employed on OLCF’s Summit supercomputer to compute UV/Vis absorption spectra for a large training set of dye molecules. This data will drive a novel ML approach to predict novel EC dyes with superior properties.
Figure:
The goal of this proposal is to develop and employ a high-performance computing (HPC)- and machine learning (ML)-driven electrochromic dye design methodology. The results from this project will be used to produce energy efficient building windows that can be manufactured at an attractive cost using roll-to-roll processing methods.

OPTIMIZATION OF PROCESSING PARAMETERS FOR METAL POWDER PRODUCTION
Principle Investigator: Dr. Andrew Heidloff
National Lab Partner: Dr. Iver Anderson , Ames Laboratory
Summary:
Additive Manufacturing (AM) technologies are redefining next generation, energy critical component/system designs and manufacturing (e.g., stationary gas turbines, heat exchangers for extreme environments, etc.). The ability to produce complex geometries coupled with rapid development of new materials capable of harsh environments allows for unprecedented energy efficiencies through AM. Gas atomization (GA) is one of the most promising methods of producing feedstock powders used in AM processes, but suffers from inefficient powder yields and poor powder quality characteristics. This follow-on project aims to further develop the current understanding of breakup mechanisms during GA by using 2D and 3D computational fluid dynamics (CFD) to study the key variables leading to enhanced efficiency/ precision and powder quality. The results will aid US powder manufacturers in optimizing GA technologies to improve powder yield/quality, reduce material and energy production costs, and expedite the availability of novel and fully developed alloy powders for the AM marketplace.

The Procter & Gamble Co will partner with Sandia National Laboratories to create an eco-system of HPC-enabled fiber manufacturing models to allow for defect-free production of solvent-free detergents with an accelerated timescale and reduced waste streams compared to traditional approaches such as build-test cycles in a project titled “Reinventing the Green Consumer Products Landscape with Material and Process Design using High Performance Computing”.

DEFECT-FREE PRODUCTION OF SOLVENT-FREE DETERGENTS
Principle Investigator: Dr. William Hartt IV
National Lab Partner: Dr. Rehka Rao , Sandia National Laboratory
Summary:
A new-to-the-world product form may revolutionize consumer cleaning products such as laundry detergent, shampoo, dentifrice, and lotions, by lowering energy usage for manufacturing and transportation and significantly reducing the carbon footprint compared to traditional products. These novel products will eliminate the need for water transportation, yet still perform effectively and receive excellent consumers reviews. However, formulation and processing of these game-changing materials are challenging. P&G desires modeling and simulation technology to theoretically determine process windows and formulate new products optimized for reduced defects. The rheology of the precursor solution, containing surfactants, polymers, and other actives, must be optimized such that fibers may be formed and solidified without instabilities such as droplet formation, fiber folding, or breakage. Process development and optimization require significant insight into these physical process for predictivity and control; process breakdowns and low yield can be costly. In this proposal, P&G will utilize expertise in rheology and process development complemented by HPC transient 3D multiphase viscoelastic flow models developed at Sandia to provide a modeling and simulation approach, using machine learning, to capture the complex rheology and advance process design. This “digital manufacturing” approach will allow for defect-free production of solvent-free detergents with an accelerated timescale and reduced waste streams compared to traditional approaches such as build-test cycles.

IMPROVING JET ENGINE LIFECYCLE ENERGY EFFICIENCY
Principle Investigator: Dr. Michael Joly
National Lab Partner: Dr. Pinaki Pal, Dr. Muhsin Ameen, Dr. Opeoluwa Owoyele , Argonne National Laboratory
Summary:
This proposal aims to quantify the impact of manufacturing uncertainties in gas turbine engines and to better assimilate lifecycle sensitivities in the development of next-generation energy-efficient technologies. Reliable film cooling drives durability and thermal efficiency of turbine stages in gas turbine engines, but is greatly sensitive to variations in the shape of cooling holes (such as, machining offset, blockage from thermal barrier coating, and surface roughness) induced by manufacturing processes. The primary objective of this proposal is to develop a machine learning technique to desensitize film cooling effectiveness to manufacturing variability. The novelty of this proposal is in the development and application of composite neural network as a surrogate of multi-fidelity computational fluid dynamics (CFD) simulations towards the development of a reduced-order model to inform gas turbine engine design practitioners of the impact of manufacturing uncertainties on the energy efficiency and durability of gas turbine engine components.

AN ICME MODELING FRAMEWORK FOR METAL MATRIX COMPOSITES
Principle Investigator: Tahany El-Wardany, Masoud Anahid , Raytheon Technologies Research Center
National Lab Partner: Mark Messner , Argonne National Laboratory
Summary:
Widespread use of Metal Matrix Composites in automotive and aerospace industries could lead to substantial energy savings by light-weighting components and increasing operating temperatures and efficiency. MMCs have complex microstructures and current material design process largely relies on iterative experimentation, leading to long material design and qualification times. A physics-based modeling approach could greatly accelerate material development by providing a direct connection between key microstructural features and the resulting material properties. This project, a collaboration between Argonne National Laboratory (ANL) and Raytheon Technologies Research Center (RTRC), would develop a physics-based, full-field model for a key MMC system, run throughput simulations on high performance computing, and develop a surrogate model using the throughput simulations as training data to connect key microstructural features to the material properties of interest. RTRC would then incorporate this surrogate model into their material design process by manufacturing materials with microstructures tailored to optimize the components performance.

LASER POWDER BED FUSION TO IMPROVE CAR PART QUALITY
Principle Investigator: Dr. Mei Li and Dr. Yang Huo
National Lab Partner: Dr. Xiaohua Hu - Oak Ridge National Laboratory
Summary:
Laser power bed fusing (L-PBF) additive manufacturing is a key enabling technology to manufacture highly complex and integrated automotive structures. L-PBF processes usually produce excessive and nonuniform residual stresses, which increase quality uncertainties and manufacture issues, leading to increases in cost and energy consumption in the form of rejected parts. We propose to extend an HPC-compatible in-house ORNL finite element (FE) code, which was demonstrated on pseudo-3D fully-coupled thermomechanical L-PBF simulations, to part scale and use it to predict temperature evolution and residual stress during L-PBF with experimental validation. The innovative multi-resolution and concurrent modeling approach adopted in this code ensures accuracy and computational efficiency, which will enable energy-efficient and high-yield, low-cost manufacturing of optimized, qualifiable automotive structures. The successful completion of this project will contribute towards reaching technical targets outlined in AMO’s Program Plan to develop additive manufacturing systems that deliver consistently reliable parts with predictable properties.

NEXT GENERATION RECYCLABLE CELLULOSE-BASED PACKAGING MATERIALS
Principle Investigator: Kelly Williams
National Lab Partner: Dr. Peter Ciesielski - National Renewable Energy Laboratory
Summary:
Fossil plastics in single-use packaging is one of the top existential problems in the world, and post-consumer collection of discarded materials continues to be elusive. Compostable packaging offers substantial energy savings relative to plastic packaging that requires recycling or upcycling in circular economy scenarios, and brands across the globe are seeking compostable options for flexible packaging. Cellulose, particularly dissolvable pulp that can be converted into high barrier packaging films, is currently in very high demand. We will leverage high-performance computing to accelerate evolution of art and science related to cellulose-derived films to meet societal demands and displace environmentally detrimental incumbent products. Specifically, molecular variations of cellulose dissolving pulp will be designed in-silico and their performance metrics, including mechanical, thermal, and barrier properties, will be predicted by large-scale simulation of polymer assemblies. The results will be used to identify production targets for next generation cellulose-based packaging materials to meet industry needs.

Principle Investigator: Dr. Joseph Shiang
National Lab Partner: Dr. Dongwon, Shin – Oak Ridge National Laboratory
Summary:
Current chemical vapor infiltration ceramic matrix composite (CVI-CMC) technology does not yet meet all requirements for commercialization in aircraft engines, in part due to the difficulty of optimizing CVI processes for batch scales and the significant capital expenses required. GE and ORNL will team to enhance ORNL’s recently demonstrated data-driven CVI simulation workflow (CVISim) by explicitly incorporating the complex chemical kinetics of the CVI process. This project will exploit high-throughput computational fluid dynamics (CFD) and modern data analytics on HPC to rapidly develop a high-fidelity CVI kinetics model. Project success will enable accurate physics, data-based forecasting of advanced processing costs, and description of the operational performance of the CVI process prior to capital equipment acquisition, simultaneously reducing scale-up risk and accelerating commercialization. Enabling the introduction of a CVI-CMC material system to both aircraft engines and land-based turbines is expected to result in significant fuel consumption reductions.

REDUCING SPRINGBACK FOR AEROSPACE AND AUTOMOTIVE APPLICATIONS
Principle Investigator: Dr. Babak Raeisinia
National Lab Partner: Dr. Victor Castillo - Lawrence Livermore National Laboratory
Summary:
The total onsite energy use for the Fabricated Metals (NAICS 332) sector in the U.S. is about 344 TBTU (with 11 MMT CO2-equiv of emissions) [1]. It is possible to reduce this energy and emissions footprint by ensuring that energy is only used when and where dictated by product performance needs. Uptake of such performance-informed processing strategies has been limited due to challenges in connecting product performance to processing parameters in real-time for control purposes. With current advancements in artificial intelligence and simulation capabilities, coupled with advanced sensors, it is now possible to overcome this challenge. This HPC effort is aimed at developing a lean, reduced-order model based on process simulation and sensor data to enable performance-informed thermo-mechanical processing of sheet metal parts. Broad adoption of such strategy across the industry would reduce the process energy of sheet metal parts, lead to development of novel products, while improving manufacturing yields.

MULTI-PHYSICS SIMULATION FOR AN EFFICIENT ABSORBENT STRUCTURE
Principle Investigator: Dr. Mel Allende and Dr. Ken Comer
National Lab Partner: Dr. Scott Roberts - Sandia National Laboratories
Summary:
Open Cell Foams (Random Foams) manufacturing, as well as papermaking, is a highly energy intensive manufacturing process. Tremendous amounts of energy can be saved if the microstructures can be designed and optimized for dewatering/drying while maintaining a desirable consumer experience.
The objectives are: To utilize a model-based approach to predict the process parameters required to efficiently and effectively utilize raw materials while also reducing energy consumption in the dewatering/drying of random foam & structured papers while generating a final product which is consumer preferred. Meeting these objectives requires optimizing a truly multi-physics problem.
In this project, The Procter & Gamble Company (P&G) will use codes developed by Sandia National Laboratories to represent the needed multi-physics with high HPC scalability. These codes will then enable P&G to design and optimize foam/fiber structures that meet the consumer needs and require much less energy and cost to manufacture.

MIRCOWAVE-ENHANCED MANUFACTURING OF CERAMIC MATIRIX COMPOSITES
Principle Investigator: Dr. Ying She
National Lab Partner: Dr. Vimal Ramanuj, Dr. Wenjun Ge, Dr. Ramanan Sankaran - Oak Ridge National Laboratory
Summary:
This project addresses the use of microwaves to intensify the manufacturing process of Ceramic Matrix Composites (CMCs) that enable light-weighting and energy efficiency improvements of gas turbines when deployed in the hot section. A conservative estimate is that CMCs can reduce thrust specific fuel consumption (TSFC) in commercial aerospace by ~2.5%, resulting in US annual nationwide energy savings of 113 TBTU. High Performance Computing (HPC) will be used to develop pore- and geometry-resolved modeling capabilities of an advanced Chemical Vapor Infiltration (CVI) process and corresponding reactor design. This will address the technical challenge of more uniform heating and temperature control, as required for manufacturing high-quality CMCs in a shorter manufacturing time. It will accelerate the development of CMCs for commercial aerospace and showcase HPC capabilities at Oak Ridge National Laboratory (ORNL).

National Lab Partner: Dr. Srdjan Simunovic, Dr. Merlin Theodore, Dr. Max L. Pasini - Oak Ridge National Laboratory
Summary:
U.S. carbon fiber (CF) annual demand reached ≈73.1 million lbs/yr in 2020 and the primary energy intensity of PAN carbonization-step is ≈13.4 TBtu/yr. Using microwave-assisted plasma (MAP), ORNL demonstrated ≈45% energy savings, ≈67% reduction in residence-time, ≈40% reduction in CF production cost at small-scale, which can lead to energy savings of ≈1.7 TBtu/yr, based on 2010 current typical technologies. Building on ORNL work, this project aims to: (i) develop robust multi-physics model and machine-learning (ML) optimization algorithms to upscale MAP-carbonization to industrial levels and (ii) further optimize and validate techno-economic viability of MAP-based PAN carbonization. Structural light-weighting will benefit from advancing MAP-based technology in U.S.-manufacturing for energy-efficiency and it will positively impact the commercial aircraft manufacturing-supply-chain (which includes Raytheon Technologies), and the reduction of CF manufacturing-energy consumption. ORNL HPC capabilities and expertise are crucial to overcome key challenges in the computationally intensive optimization, testing, and validation of ML-driven MAP systems.

QUENCH HEAT-TREATMENT PROCESSES FOR GAS TURBINE PARTS
Principle Investigator: Dr. Michael Glavicic and Dr. Chong Cha
National Lab Partner: Dr. Ramanan Sankaran (ORNL) and Dr. Ik Jang (LLNL)
Summary:
To manufacture light-weight, advanced metal alloy components for gas turbine engines, quench heat-treatment processes are typically used. By quenching the component from elevated temperatures, the alloy sometimes undergoes a solid-state phase transformation which produces special microstructures with the required, enhanced mechanical properties. However, the quenching can also lead to cracks forming in the component. Addressing the quench cracking problems adds a significant burden to the cost, schedule, and energy demand of manufacture. Currently, optimizing the quench process to mitigate or avoid the cracking is performed largely by trial-and-error, relying heavily on costly experimental (thermocouple) trials to understand the local thermal gradients which cause the cracks to form. In this work, high-performance computing is employed to establish the ability of modern CFD (computational fluid dynamics) to alleviate or wholly replace the experimental quenching trials by virtual testing.

Electrochemical energy storage technologies that are durable, efficient, energy dense, cheap, safe, and industrially scalable are highly demanded by a wide range of applications. Solid-state battery technologies are promising in this regard, but they remain challenged by difficulties in simultaneously achieving energy-efficient processability, mechanical durability, and efficient performance of manufactured electrolyte components. Toyota Research Institute of North America has developed a new class of Li-ion solid-state electrolytes that promise highly efficient performance and easier processability and therefore are expected to enable practical production of solid-state batteries. However, optimizing processing requires understanding the critical connection between mechanical robustness, ionic transport, and thermodynamic properties, which is very challenging utilizing available experimental tools due to the high levels of structural complexity. This project integrates experiments with a multiscale modeling approach that can offer the necessary insights to advance this area and accelerate the deployment of practical and easily processible solid-state batteries.

National Lab Partner: Dr. A. Cody Nunno (ANL), Dr. Prithwish Kundu (ANL), and Dr. Victor Castillo (LLNL)
Summary:
This research furthers VAST® TriFluid™ combustor and VAST Power Cycle™ design optimization for ~70% higher net power through a single expander, and ~24% better single turbine efficiency, with NOx and CO emissions below mandates, without catalysts, or ammonia.
To prevent state-wide blackouts from large wind/solar dropouts, California requires rapid 10-minute and 5-minute dispatch Peaker turbines, and 1-minute emergency dispatch. Frequent ramping severely harms turbines, increasing replacement costs. Clean air emission mandates cause high catalyst expenses. Emission control is difficult during rapid turbine startups, for pilot flames, and hydrogen combustion.
VAST® FastRamp™ turbines offer higher profitability with faster dispatch over >5% to <50% capacity use with renewable energy constraints. VAST’s patented independent temperature control minimizes cyclic fatigue, improving relative operating life. Accurate temperature control extends blade life. FastRamp turbines enable >40% US renewable grid penetration and international deployment. They create a profitable new niche between peakers and constrained combined cycle turbines.

National Lab Partner: Dr. Hariswaran Sitaraman, Dr. Shashank Yellapantula, Dr. Vivek Bharadwaj, Dr. Marc Henry de Frahan - National Renewable Energy Laboratory
Summary:
Thermolyzer™ is the only technology that can convert all waste hydrocarbon materials cleanly and safely into a fuel gas and salable byproducts. This means that tons of plastics now in storehouses can be converted into energy, thereby conserving non-renewable fossil fuels. The impact on the U.S. economy can be huge. However, pyrolysis of plastics is a complex process. The feedstock material that is of high variability is continuously gasified creating multiple species as it gets converted to a complex synthesis gas and carbon. The geometry and temperature gradients within the reactor are also complex. Thus, computational modeling of the reactor using high performance computing is essential in order to understand the physico-chemical interactions and to derive the best operating conditions for maximum efficiency. This project will provide the capability to achieve efficient larger-scale Thermolyzer systems (~200 ton/day capacity) that can significantly reduce the backlog of scrap plastics in the US.

National Lab Partner: Dr. Ram Devanathan - Pacific Northwest National Laboratory
Summary:
This HPC4EI proposal seeks to develop a data driven approach to link features of the material and manufacturing processes to the mechanical properties of thermoplastic composite parts. This work will leverage data from physics-based commercial codes for manufacturing simulation and micromechanical analysis. There is a need to develop and manufacture lightweight materials with enhanced performance to improve the energy efficiency of automobiles. With outstanding strength to weight ratio, good fatigue resistance and good corrosion/fire resistance, composite materials are well positioned to meet the lightweight challenge. However, computational tools are needed to develop composites with enhanced performance given the large number of parameters that can be tuned to improve the performance. The proposed work will use high performance computing (HPC) and data analytics to optimize the design, shorten the time to market and generate reduced order models that are ultimately usable by U.S. industry without the need for HPC resources.

TITANIUM ALLOY DEVELOPMENT FOR ADDITIVE MANUFACTURING
Principle Investigator: Dr. Tahany El-Wardany, Dr. Ranadip Acharya - Raytheon Technologies Research Center (RTRC)
National Lab Partner: Dr. Victor Castillo - Oak Ridge National Laboratory
Summary:
Raytheon Technologies Research Center (RTRC) in collaboration with Oak Ridge National Laboratory (ORNL) proposes use of model-based tools to design alloys for additive manufacturing (AM) in order to obtain as-desired microstructure for performance improvement in aerospace and automotive applications. The performance and cost of AM products still controls the business value of deploying AM to replace conventional manufacturing processes. The digital benefit of digitally designing a component and rapidly manufacturing it through AM is often lost due to extensive experimental iterations to remedy poor performance of fabricated components. The lack of performance is often attributed to intrinsic defects formation and undesirable microstructural features since the alloy composition and microstructure are not designed optimally for the given application. RTRC and ORNL will use HPC based phase-field simulations along with experimental validation to design novel Ti alloy compositions based on forming fine equiaxed grains during AM to potentially replace currently used wrought Ti alloys.
