Projektbereich B: Modellbildung und Simulation

Research Area B: Model development and simulation

Chemically reacting flows are influenced significantly by the presence of walls. This applies to various processes of practical and scientific relevance, such as the formation of pollutants or deposits which are influenced by the presence of walls and catalytic effects. For this reason near-wall reacting flows impact innovative concepts in the fields of energy conversion processes (internal combustion engines, gas turbines, power plants) and chemical engineering. Despite the relevance of near wall reactive flows, underlying mechanisms and their mutual interactions are presently not well understood.

The models of these mechanisms (e.g. heat and mass transfer, formation of near wall turbulence, chemical reactions near walls) are developed as well as isolated processes simulated within research area B. The insights of these models serve both the understanding of the generic processes of research area A and the simulation of the lead examples of research area C. In order to be able to properly simulate the two lead examples “internal combustion engine” and “exhaust gas system”, mainly typical engine relevant substances (isooctane, methane, lubricants) and SCR substances (urea-water solution) are investigated.
