A Wing-Body Fairing Design for the DLR-F6 Model: A DPW-III Case Study

Abstract

The work presented herein has been performed in preparation of the Third AIAA CFD Drag Prediction Workshop to be held June, 2006 at the AIAA 24 th Applied Aerodynamics conference in San Francisco, California. The purpose of this work is to provide a new test case to address a problematic issue related to the inability for the industry-wide state-of-the-art CFD to achieve asymptotic grid convergence for cases with moderate-to-large amounts of flow separation. Two wing-body fairings have been designed for the DLR-F6 model geometry. The first fairing greatly alleviates the side-of-body separation near the wing upper-surface trailing-edge, while the second fairing has completely removed this separation bubble. These geometries will be made available for public release, although only the second fairing will be a subject of study in the next workshop.
