My recent research activities are in turbulent fluid flows with complex chemical reactions and radiative heat transfer. This is acomplished through high-performance parallel computations and the method is called Direct Numerical Simulation (DNS). These types of simulations resolve the finest micro-scale turbulent structures and offer reliable data for deeper understanding of the physical phenomena as well as for collecting important statistical quantities or for verification of other models. The application problems are related to engineering with energy conversion as e.g. combustion, torrefaction of biomaterials, droplet formation in microfluidic channels or decreasing of hazardous emissions from passenger cars. 

As part of the team of SimDataLabs I organize teaching courses in parallel computations and support engineering users which face challanges in modelling heat and mass transfer problems when using the supercomputers of SCC.
