Since joining NEAR, Dr. Chou has worked on several commercial reusable launch vehicle (RLV) aerodynamic designs. These have included reentry vehicle CFD modeling, RLV aerodynamic characteristics analysis, and RLV wake CFD analysis for parachute deployment. Currently, he is the principal CFD research scientist working on aerodynamics of reusable launch vehicles. Prior to working at NEAR, he worked as a CFD research scientist at Hewlett Packard. In addition, Dr. Chou was an Aerodynamics Engineer at British Aerospace, performing research in aerodynamics modeling and flight simulation from 1985 to 1990. He was involved in the development of aerodynamic models for the U.S. Navy EA-6B, BAe-146 and BAe-J31 projects. Dr. Chou has extensive experience on CFD-related software such as GRIDGEN, HYPGEN, OVERGRID, Chimera Grid Tool, PEGASUS, GRIDTOOL-VGRID, OVERFLOW, CFL3D, LAURA, FUN3D and Stanford-PSIM. He is one of the pioneers working in the field of kinetic-based CFD algorithms today. Dr. Chou was one of the principal developers for the 3D DSMC-KFVS hybrid code at Stanford University. Collaborative efforts in the field of CFD with a closely aligned group at Stanford University are providing Dr. Chou with a variety of new CFD technologies.
