Scale Resolving Simulation of Nacelle / lower-Wing Interferences near High Speed Stall Conditions

Kurzfassung

Large and efficient ultra-high bypass ratio engines need to be closely coupled to the wing resulting in strong interferences between the flow around the engine nacelle and the wing. Especially for transonic flows, these flow interferences are difficult to predict with conventional statistical turbulence models. Therefore, the present work, which is part of the DFG-FOR2895 project on "Highspeed stall", focuses on improving and validating a turbulence resolving method for this kind of flow.
