Abstract
The vortex structures on the leeward side of a large delta wing have been investgated by means of digital particle image velocimetry. The measurements were carried out in a plane crosswise to the main flow direction. The large spatial dimensions of the interesting flow structure required a special technical solution: Two CCD cameras were employed to record neighboring regions of the flow field simultaneously. A combination of four single-pulsed laser oscillators, in which two of them fired simultaneously, generated an extended light sheet of sufficiently high intensity in order to image micron particles added to the flow. In this way, the whole vortex system could be observed at Reynolds numbers Re > 10 000 000
