The Multi-Physics Computations group at Argonne National Laboratory is seeking to hire a postdoctoral appointee on the topic of CFD modeling of internal combustion engines fueled by low-carbon fuels (H2, NH3). The successful candidate will leverage high-performance computing (HPC) resources at the Laboratory to perform CFD simulations of low-carbon fuel injection, mixing, combustion, and emissions. The successful candidate’s research will involve synergistic collaborations within a multidisciplinary team comprised of fellow postdoctoral appointees and staff scientists with computational fluid dynamics and machine learning expertise, with the goal to enhance predictive capability and scalability of multi-scale and multi-physics simulation codes. + Perform high-fidelity CFD simulations of complex physical processes in internal combustion engines (ICEs), such as fuel injection, combustion, heat transfer, etc. + Improve, develop, and implement CFD sub-models necessary to enable predictive ICE simulations, specifically for low-carbon fuels (e.g., H2, NH3), when using commercial or open-source CFD software (e.g., CONVERGE or similar). + Work in a multidisciplinary team involving engine modelers and computational scientists to run the simulations at-scale using both current large clusters and the next generation supercomputing architectures. + Work to consistently meet priorities and deadlines set by the research sponsor(s). + Collaborate with other staff scientists and postdocs in the group. **Position Requirements** + Ph.D. in mechanical/aerospace/energy engineering, applied mathematics, chemical engineering, or a related discipline. + Experience with modeling three-dimensional multiphase turbulent reacting flow applications using CFD codes (e.g., CONVERGE, OpenFOAM, etc.). + Experience with multi-dimensional CFD internal combustion engine modeling. + Knowledge of low-carbon fuels (H2, NH3) chemical and physical properties. + Knowledge and experience with high performance computing. + Knowledge and experience with CFD code development. + Knowledge of parallel scientific computing. + Ability to meet project needs and tight deadlines. + Present and publish results in peer reviewed papers and/or journal articles. + Skilled verbal and written communication skills at all levels of the organization. + Collaborative skills at all levels of the organization. + Ability to model Argonne’s core values of impact, safety, respect, integrity, and teamwork. + Ability to make our laboratory a safe, welcoming, inclusive, and accessible environment where all can thrive. Preferred Qualifications: + Experience with CFD modeling of H2 and/or NH3 internal combustion engines. + Experience with CONVERGE CFD software. + Experience in geometry manipulation with computer-aided design software. **Job Family** Postdoctoral Family **Job Profile** Postdoctoral Appointee **Worker Type** Long-Term (Fixed Term) **Time Type** Full time _As an equal employment opportunity and affirmative action employer, and in accordance with our core values of impact, safety, respect, integrity and teamwork, Argonne National Laboratory is committed to a diverse and inclusive workplace that fosters collaborative scientific discovery and innovation.
