AEROSPACE RESEARCH INTERESTS
Propulsion and Computational Fluid Dynamics
Our focus is on developing advanced engineering fluid dynamic and multi-disciplinary simulation and design tools primarily for propulsion and aerospace systems. We have developed new solution procedures for the main flow path of aircraft jet engines, innovative gas-turbine cycles, rocket engine feed systems and cooling tubes, propeller design, and centrifugal compressors. We have also designed new drag reduction devices for transportation systems. Many of our solution procedures use the latest turbulence modeling strategies such as detached-eddy or hybrid Reynolds-averaged/large-eddy simulation models.
We utilize advanced distributed- and shared-memory parallel computing techniques in our large-scale simulations. Recent research has also focused on using graphical processing units to reduce simulation times and price/performance ratio by over two orders in magnitude.
The Wright-Patterson Air Force Research Laboratory (AFRL), Lawrence Livermore National Laboratory, Los Alamos National Laboratory, GenCorp Aerojet, and the University of California have funded our research.
