Postdoctoral Appointee – Spectral Element Methods

Argonne National Laboratory

Argonne, IL

Job posting number: #7116439 (Ref:414456)

Posted: November 19, 2022

Application Deadline: Open Until Filled

Job Description

The Multiphysics Engine Computations group at Argonne National Laboratory is seeking to hire a postdoctoral appointee. The successful candidate’s research will involve synergetic collaborations with a multi-disciplinary team involving engine modelers and experimentalists, and computational scientists to enhance the predictive capability for next-generation engine modeling code.

Perform high-fidelity Computational Fluid Dynamics (CFD) simulations of gas turbine and internal combustion engines using spectral element method (SEM). Implement submodels for turbulence, two-phase flow, and combustion into SEM codes. Perform scalability studies and port these simulations on leadership class supercomputing resources, identify and improve the bottlenecks in scaling the simulations.

Position Requirements

  • Ph.D. in mechanical/aerospace engineering, applied mathematics, chemical engineering, or a related discipline.  

  • Expertise in Nek5000 or other comparable spectral element method codes.

  • Experience in running high-fidelity simulations on leadership class supercomputers.

  • Knowledge of large scientific code management and optimization is desirable.

  • Knowledge of performing scalability studies to identify and improve bottlenecks in large codes.

  • Understanding of high-order methods for fluid flows.

  • Extensive experience in geometry optimization and mesh generation with computer-aided design software.

  • Collaborative skills, including the ability to work well with other divisions, laboratories, and universities.

  • Communication skills at levels of the organization.

  • Understanding of turbulent combustion modeling is desired.

  • A successful candidate must have the ability to model Argonne’s Core Values: Impact, Safety, Respect, Integrity, and Teamwork.

What will put you ahead:

  • Experience in two-phase flow applications, turbulence modeling, internal combustion engine theory and operation is desirable.

  • Experience in interdisciplinary collaborative research is desirable.
