Our laboratory is interested in fluid mixing at high temperatures, pressures, and velocities. We are also interested in additional physics in these problems such as multiphase flows, and magnetohydrodynamic forces. These types of problems arise in hypersonic propulsion, detonation engines, inertial confinement fusion, astrophysics, and refrigeration technologies. We use both simulations and experiments to perform our research. Our laboratory operates a shock tube facility and we are constructing a liquid-fueled detonation tube. We use high-speed laser based diagnostics (e.g. PIV, PDPA, high-speed imaging) to measure fluid conditions in these experiments. On the simulation side of our research, we develop models for implementation in hydrodynamics codes and run simulation of shock-driven multiphase and magnetohydrodynamic problems. We use both in-house codes and codes maintained by DoE/NNSA and DoD laboratories.
