Kurzfassung
Blind RANS CFD solutions were obtained for the N-47 wing body with three different wing tip devices: Küchemann tip (basic configuration), fence tip and large winglet. Onflow conditions are M=0.85 and a high Reynolds number Re=54.2 mill, corresponding to cruise conditions. Solutions were obtained on unstructured hybrid meshes using the TAU solver. Solutions were obtained at various incidences and at constant lift to evaluate performance. Different adaptation mesh refinement procedures were used to improve resolution of flow regions of interest. One and two-equation turbulence models were used. The three wing tip devices were compared by analysing results of pressure distributions, local distributions of force and moment, surface contours and skin friction lines.
