Lemont, IL

Job posting number: #7066185 (Ref:408232)

Posted: May 8, 2020

Application Deadline: Open Until Filled

Job Description

Perform high-fidelity Computational Fluid Dynamics (CFD) simulations of Internal Combustion Engine (ICE) flows using spectral element method (SEM). Develop tools to generate SEM grids for complex, moving domains in a seamless fashion. Implement submodels for turbulence, two-phase flow, ignition, 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.

 

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.

  • 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.
  • Good knowledge of performing scalability studies to identify and improve bottlenecks in large codes.
  • Understanding of high-order methods for fluid flows.
  • Strong collaborative skills, including the ability to work well with other divisions, laboratories, and universities.
  • Strong communication skills.
  • Understanding of turbulent combustion modeling is desired.
  • Experience in two-phase flow applications, turbulence modeling, internal combustion engine theory and operation is desirable.
  • Experience in interdisciplinary collaborative research is desirable.
  • Candidates should have a Ph.D. in mechanical/aerospace engineering, applied mathematics, chemical engineering, or a related discipline.  
  • A successful candidate must have the ability to model Argonne’s Core Values: Impact, Safety, Respect, Integrity, and Teamwork.
