Drag prediction of the DLR-F6 configuration

Out of a host of experimental aerodynamic data available for the DLR-F6 configuration a set of reference test cases has been chosen for the second AIAA drag prediction workshop. Participants of the workshop were invited to use state-of-the-art tools for computational aerodynamics to compute these test cases and provide numerical data for integrated force coefficients and flow phenomena with the aim to assess the quality of today's flow solvers for transonic viscous flow about complex geometries. We present results for the block-structured flow solvers FLO 107-MB and TFLO2000, which are based on numerical schemes by the third author. An incidence sweep and a grid refinement study at design conditions are shown, as well as an evaluation of the prediction of flow phenomena. Two different numerical schemes for convective fluxes and four different turbulence models have been used in this work. A comparison between the different numerical methods and turbulence models is particularly emphasized.
