RANS Turbulence Modeling for Aerospace Applications. Development, Validation and Prospects

This talk gives an overview over selected topics in the development of RANS turbulence modeling for aerospace applications. The basic calibration of RANS models is revisited and implications for non-canonical flows with streamwise pressure gradients, surface curvature and vortical flows are outlined. The aim is to bring together the view from RANS modeling with experimental investigations and theoretical as well as empirical findings of turbulent flows regarding the mean velocity field and the Reynolds stresses. Then some comments and implications for data-driven turbulence modeling approaches are given. Finally, some thoughts for future prospects are given.
