Abstract

This paper presents the objectives for the new International Vortex Flow Experiment (VFE-2), and its organization within an RTO Task Group is outlined. The available wind tunnel models as well as the applied experimental techniques are described briefly. Results of Pressure-Sensitive Paint (PSP) measurements at DLR Goettingen showed a first insight into the flow mechanisms. Additional CFD results from numerical solutions of the RANS equations as calculated by EADS Munich led to an initial understanding of the flow details and allowed a proper wind tunnel set-up for the Particle Image Velocimetry (PIV) experiments at DLR Goettingen. These measurements showed the details of the flow field in the vicinity of the wing in excellent agreement with the CFD results.
