Abstract
A new test case of a symmetric wake at adverse pressure gradient (APG), which emulates the flow conditions over the flap of a modern high-lift system, is presented for the targeted improvement of RANS turbulence models towards accurate maximum lift prediction. The model improvements will be based on the identification of the right model term(s) which have to be modified in the future so that the modified model yields the test case data with high accuracy. For this purpose, highly resolved data from wind tunnel experiments and a complementary numerical experiment, see, were provided.
