The area of my research interests is theoretical and computational fluid dynamics with an emphasis on turbulence phenomena in aerodynamics and flight propulsion as well as turbulence in fluids with complex thermodynamics. My primary tools for investigating physical problems are numerical modeling and simulation on supercomputers.
I have a strong background in turbulence modelling and in the development of highly accurate and computationally efficient numerical methods for Large Eddy Simulation (LES) and Direct Numerical Simulation (DNS). Concerning fundamental flow phenomena, I am interested in the transition from laminar to turbulent flow, stratified turbulence and waves in the atmosphere, interactions of turbulence with shock waves in compressible flows at low and high Mach numbers, mixing and combustion in trans- and supercritical flows with strong real-gas effects, and the interaction of turbulence with phase change/cavitation in multiphase flows, for example.
In view of the increasing popularity of LES in engineering, I am also developing numerical methods that allow for an efficient and largely automated simulation of complex flow geometries. Some examples are the modelling of wall boundary layer flows at high Reynolds numbers, methods for representing moving geometries on stationary Cartesian grids, dynamic grid adaptation, and fluid-structure interaction. Representative LES applications in current research projects include, for example, unsteadiness of shock- turbulence interaction in the inlet of a SCRamjet engine and the improvement of the mixing and combustion at supersonic speeds, a reactor for gas-dynamic generation of nano-particles, fluid-structure interaction in rocket nozzles, combustion of supercritical fluids in rocket thrust chambers, delta-wing and slat-wing-flap high-lift configurations for aircrafts as well as the prediction of cavitation in fuel injectors for automotive Diesel engines.
The mentioned methods and applications cover a rather broad field; what they have in common is the intrinsic coupling of physical, mathematical and numerical modelling and my desire to investigate challenging contemporary problems.
