Abstract

Three-dimensional, unsteady flow fields of a pitching low aspect ratio wing were measured by tomographic PIV [6] in air. The analysis of the vortex dominated flow field provides a deeper understanding of vortex interaction and three-dimensionality of the low Reynolds number (Re ≈ 10,000) flow. In order to recover the complete flow field the measurement set-up was designed to be traversable. A high spatial resolution and a large volume thickness could be achieved by a set of high sensitive sCMOS cameras. A specific feature of this campaign was to locate the measurement domain directly above the flat-plate-wing surface. Evaluation of the measurement data is performed by DLR in-house software. A selection of measurement results of this highly complex flow is presented in this paper.
