Task:
In the future, the whole transport sector must be supplied by sustainable energy sources. For flight traffic, sustainable avia-tion fuels (SAFs) are discussed as a future source of propulsion. Naturally, there are numerous challenges in the areas of injec-tion, spray ignition and flame propation that must be evaluated.
Within this thesis, the CFD model of the ports and the combustion chamber of compression-ignition internal combustion engine are to be set up in a commercial CFD-code. Afterward, the models for turbulence, fuel jet and the fuel chemistry are to be implemented. The CFD-model will be used to simulate the turbulent in-cylinder flow after inlet-valve closing, the spray atomization, the ignition, and the combustion. A validation against measurements from combustion chamber and engine test bed will be part of the work. An analysis of the results with respect to in-cylinder flow and its impact on the combustion process has to be carried out. The work is to be documented in a master thesis.
