Abstract

The rounded leading edge shapes include low, medium, and high leadingedge radii. The experimental data base is used to expand the knowledge about the flow topology and flow physics and to verify and validate computational codes. This paper focuses on the flow topology around the VFE-2 delta wing with medium rounded leading edges at different Reynolds numbers and angles of attack using various turbulence models, especially RANS and hybrid models such as DES and DDES. The overall goal is to understand more fully the flow topology for these non-sharp leading-edge delta wings. Previous numerical studies on the VFE-2 delta wings have been limited, with Londenberg showing results for the sharp leading-edge delta wing under transonic conditions and Chiba and Obayashi performing calculations of the dual primary vortices that form on the medium radius leading edge. The topology of the dual primary vortices is especially interesting, and formed the basis for the majority of papers in two special sessions at the 46th AIAA Aerospace Sciences Meeting and Exhibit in 2008.
