My multidisciplinary research team works in the field of computational fluid dynamics (CFD) in energy technology. In particular, we mostly utilize a modern high-performance computing technique called Large-Eddy Simulation (LES) in order to resolve liquid and gas flows in various applications. Also hybrid LES-RANS approaches are being used in the team. Our simulation platform is primarily the open source code OpenFOAM. Present doctoral thesis projects are involved with heat transfer, reacting flows, two-phase flows and hydrodynamics of energy efficient ships. Novel computational research topics involve development of modern, low-temperature combustion concepts for marine engines, simulation of cavitating and boiling flows,  primary atomization of biofuels and development of compact liquid cooling concepts.  We work in close collaboration with experimentalists. Our research methods are broadly applicable in various multidisciplinary applications in the society.
