Postdoctoral Appointee - Heavy-Duty Internal Combustion Engine Modeling

The Advanced Propulsion and Power department at Argonne National Laboratory is seeking to hire a postdoctoral appointee. The successful candidate’s research will involve synergistic collaborations with a multidisciplinary team comprised of fellow postdoctoral appointees, experimentalists, and staff scientists, with computational fluid dynamics (CFD) and artificial intelligence/machine learning (AI/ML) expertise, with the goal to enhance predictive capability and scalability of multi-scale and multi-physics simulation codes.

The prospective postdoctoral appointee will perform multi-physics and multi-scale CFD simulations of internal combustion engines involving modeling of multi-phase flows, turbulent combustion, heat transfer, and emissions by further developing commercial/in-house codes and making use of high-performance computing (HPC) tools.

• Develop accurate, computationally efficient physics-based and data-driven CFD models which the candidate will use to simulate the chain of physics and chemistry involved with fuel injection, spray-wall interaction, fuel-air mixing, turbulent combustion, abnormal combustion (e.g., knock, pre-ignition), and emissions formation.
• Perform CFD simulations of fuel injection, mixing, and combustion processes for heavy-duty internal combustion engines using High-Performance Computing.
• Improve the computational efficiency and accuracy of existing physics-based and data-driven fuel injection and spray models and integrate them into simulations of propulsion systems.
• Perform high-fidelity reacting flow simulations that involve both conventional and alternative fuels.
• Work as a part of a multidisciplinary team involving experimentalists, CFD experts, AI/ML specialists, and computational scientists to enable cutting-edge CFD modeling & simulations on HPC clusters and next-generation supercomputing architectures.
• Collaborate with other staff scientists and postdocs in the group.
• Work effectively to meet priorities and deadlines set by the research sponsor(s).
