Germany Modeling combustion in technical combustion devices is
challenging, because of the multi-scale character, complex
geometry, flow, and mixing, and the multitude of different
interacting processes, including turbulence, chemistry, spray
formation, spray dynamics and evaporation, radiation, and
pollutant formation. Here, using the example of aircraft engine
combustors, we will first assess the importance of different
combustion regimes for the application. Based on this knowledge,
suitable combustion models will be developed. The application in
simulations of novel combustor design concepts shows that for
liquid fuel combustion, small details in the spray models have a
leading order influence. Finally, the application of the
combustion models in predictions o
