Postdoctoral Appointee - Multi-phase Flows

Argonne National Laboratory

Lemont, IL

Job posting number: #7074887 (Ref:409370)

Posted: February 8, 2021

Application Deadline: Open Until Filled

Job Description

Perform Computational Fluid Dynamics (CFD) simulations of turbulent multiphase flow and erosion development inside fuel injectors using High-Performance Computing (HPC) tools. Build multi-fidelity models for two-phase flows by fusing data from state-of-the-art experimental measurements with high-fidelity simulation predictions. Improve the accuracy of two-phase flow models for: 1) phase change of multi-component mixtures, and 2) dynamic coupling of nozzle flow with spray simulations for both diesel and gasoline direct injection applications. 

The successful candidate’s research will involve synergetic collaborations with a multidisciplinary team involving engine modelers and experimentalists, and computational scientists to enhance the predictive capability of engine modeling codes.

Considerable:

  • Knowledge of multi-dimensional code development (in C++/C/Fortran) for two-phase and/or multiphase flow applications, turbulence modeling, internal combustion engine theory and operation, and parallel scientific computing is required.

Good:

  • Knowledge of deep learning (in TensorFlow, PyTorch, etc.) for multi-fidelity modeling, regression tasks, management and analysis of big data, and parallel scientific computing is desired.

  • Experience in modeling and simulation of three-dimensional two-phase and/or multiphase flow applications using CFD codes (e.g. CONVERGE, OpenFoam, etc.) is desired.

  • Experience in geometry manipulation with computer-aided design software is desired.

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

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

  • Good communication skills. 

What will put you ahead:

  • Experience in interdisciplinary collaborative research is desirable. 

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

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