He received his Ph.D. in Aerospace Engineering from the University of Kansas in 1991. Prof. Cheng’s research interest is in the areas of algorithm, model, and code development for high-fidelity physics-based numerical simulations, such as computational fluid dynamics, turbulence and transition, aeroacoustics, shock-boundary layer-vortex interaction, continuum-rarefied gas flows, plasma flows with EM waves, multi-phase flows, homogeneous and heterogeneous chemical reactions, fluid-structure interaction, in-depth pyrolysis of charring ablator, radiation, chemical propulsion systems (liquid and hybrid rocket engines), nuclear thermal propulsion, turbomachinery, bio-fluid flows, pollutant transport, etc.
