Job Description
What You Will Do
The Fluid Dynamics and Solid Mechanics Group (T-3) of the Theoretical Division seeks outstanding candidates for a graduate research assistant position in multiphase flow theory and modeling.
Successful candidates will conduct research in a combination of topics including theoretical and computational fluid-structure interactions, compressible multiphase flows, and related model and algorithm developments.
The Fluid Dynamics and Solid Mechanics Group (T-3) conducts research in theoretical and computational continuum dynamics including modeling and simulation of fluids and deforming solids over multiple length and
time scales. The group's portfolio of research projects places an emphasis on coupling advanced models and numerical methods for materials dynamics at all velocities and with coupled physical processes, including
large solid deformation, multiphase flows, chemical reactions, phase change, heat and mass transfer, and combustion. This is a multi-disciplinary group with experience in diverse fields of engineering, physics,
and applied mathematics. Our customers include the National Nuclear Security Administration's Nuclear Weapons Program, other Department of Energy offices, the Department of Defense, and private industry.
Collaborations with academia are strongly encouraged.
