Propulsion and Energy
The propulsion and combustion group conducts fundamental and applied research in a wide range of areas, including monopropellant rocket thrusters, high-pressure cryogenic combustion phenomena, unsteady spray combustion dynamics, combustion instabilities in lean-premixed gas turbine engines, underwater/ramjet propulsion, solid propellants, and modern energetic materials. The numerical program specializes in large eddy simulation of combustion phenomena. Our research programs are devoted to improving our understanding of the reacting and non-reacting flow physics that control the performance of rocket and air-breathing engines. Main research subjects are as follows:
- Development of earth-based lander testbed for space flights and mono- and bipropellant thrusters for attitude control of upper stage space rockets
- Lean-premixed hydrogen combustion technology for low-emission gas turbine engines (combustion dynamics, flame structures, stabilization mechanisms, exhaust emissions)
- Robust and massively-parallel numerical simulations for unsteady reacting flows in gas turbines and rocket thrust chambers
