Broadly speaking, we combine fundamental high-speed compressible computational fluid dynamics (CFD) with problems related to space exploration and geophysical flows. Current active areas of research include:
Modeling supersonic parachute inflations for landing spacecraft on Mars
Particle laden flow modeling related to plume-surface interactions during powered descent
High-speed shock/droplet interactions
Hybrid rocket combustion modeling for SmallSat Propulsion
Modeling geo-physical phenonema, such as Yardangs on Earth and Mars, and the plumes on Enceladus
