The overall research interests of our group are in numerical simulation, analysis, and modeling of single- and multi-phase turbulent flows. Numerical simulations have acquired an important role in a number of engineering and scientific disciplines. Our work is directed towards using numerical simulation as a tool, where appropriate, to understand fundamental aspects of fluid systems and to develop and assess methods for practical applications. Specific interests include research on multi-phase (gas-solid) flows, turbulent boundary layers, heat transfer in gas turbines, and massively separated turbulent flows. Several hierarchies of numerical simulations of the Navier-Stokes equations are performed, including Direct Numerical Simulation (DNS), Large Eddy Simulation (LES), Detached-Eddy Simulation (DES) and Reynolds-averaged Navier-Stokes (RANS) computations.
- Influence of inter-particle collisions and wall-roughness on gas-solid turbulent flows.

- Simulation and modeling of the flow and thermal fields in vane-endwall passages of gas-turbine engines.
- Prediction of separated flows using Detached-Eddy Simulation.
- Extension of Detached-Eddy Simulation for shallow separations and attached boundary layers.
