Kurzfassung
The aviation industry significantly contributes to the overall anthropogenic climate impact and this is expected to grow substantially due to the ever increasing air traffic. Contrails have a significant influence on the aviation climate effect. The study of contrail formation is of great importance in order to find viable solutions mitigating its influence. It was shown that the jet after the exhaust of an airplane engine can strongly control the further contrail life cycle and therefore its radiative impact. This master's thesis aims to investigate the evolution of a turbulent jet flow behind an aircraft engine at typical atmospheric conditions with the Large Eddy Simulation model EULAG. For this purpose a model setup was adapted and high resolution three dimensional simulations were performed. Various physical and numerical sensitivities of the model configuration are studied and the results are validated against reference data.
