Abstract

The vortex structures on the leeward side of a large delta wing have been investigated by use of laser sheet imaging (LSI) and particle image velocimetry (PIV). The measurements were carried out in a plane crosswise to the main flow direction. With LSI, the structures of the seeded flow have been visualized. With PIV, the local distribution of velocity has been derived from pictures of the tracer particles by means of digital cross-correlation. In both cases, the whole vortex system could be observed at Reynolds numbers Re > 10 000 000.
