Abstract

A sequence of computations for the DLR-F6 wing-body configuration with and without the FX2B fairing was carried out using Tenasi, a node-centered, finite volume unstructured flow solver. All simulations were carried out at a Mach number of 0.75 and at two different Reynolds numbers (3×10⁶ and 5×10⁶). Significant sensitivity of the lift and drag coefficients to Reynolds number was observed. Lift, drag and moment coefficients along with pressure distributions were compared to experimental data for the DLR-F6 wing-body configuration (Re = 3×10⁶) and were in good agreement. A turbulence model as well as a grid refinement study was carried out for the DLR-F6 with FX2B fairing (Re = 5×10⁶). Lift, drag and moment coefficients are compared to other computations for the DLR-F6 with FX2B fairing.
