The method of Computational Fluid Dynamics has become an indispensable tool in the scientific research as well as in the modern engineering design and development. The increasing computer power during the last decades allowed for more and more detailled numerical simulations, which deepened the insight and understanding of physically highly complex flow problems involving complicated flow geometries, turbulence, chemical reactions, phase change, etc.. In many cases, however, the numerical attempt to resolve directly all physically relevant scales strongly exceeds by far the available computing resources. Therefore, all the numerically unresolvable but relevant effects have to modeled adequately to obtain reliable computational results. Especially in engineering flow configurations, which are typically very complex, the approach of numerical simulation is only viable, if appropriate models are provided.
The research in the present area is in particular focused on the modeling and numerical simulation of turbulent reacting flow as well as subcooled boiling flow.
