Vortex-Airfoil Interaction and Application of Methods for Digital Fringe Analysis.

Abstract

The interaction of convected vortices with different airfoils was investigated in a transonic duct and a shock tube flow. Different kinks of separation and secondary vortex generation have a governing influence on airfoil-vortex interaction. Steep sound waves propagating upstream are generated at the leading edge. A system for digital processing of flow interferograms has been developed.
