A New Vortex Flow Experiment for Computer Code Validation

Abstract

In this paper the present knowledge on the vortex formation on slender delta wings is summarized. The interference mechanisms between primary and secondary vortices as well as the vortex breakdown phenomenon are especially emphasized. The effects of Mach number and Reynolds number are treated separately and the differences in the flow around wings with sharp and rounded leading edges are discussed. The experimental details necessary for the validation of numerical methods are derived and a brief review of relevant modern experimental techniques is given. Finally a configuration suited for a new International Vortex Flow Experiment (VFE-2) as well as a corresponding test program are presented.
