Summary

In the aerodynamic industrial design process, the use of numerical simulation is of ever increasing importance. In order to adequately capture flow features such as pressure-induced separation or shock-boundary-layer interaction, an appropriate representation of turbulence is needed. This contribution summarizes the efforts undertaken at TU Berlin to develop, implement and validate advanced linear and non-linear models in the aerodynamic flow solvers FLOWer and TAU in the framework of MEGAFLOW and related projects. The accuracy of the approaches is discussed on various cases and statements with respect to their computational performance are given. The results indicate that improved predictive accuracy can be obtained from advanced Eddy-Viscosity Models at a moderate computational surplus.
