Summary

The separation phenomena on a circular cylinder in cross-flow and on an inclined prolate spheroid are studied experimentally at subsonic velocities. On the circular cylinder the steady and unsteady surface pressures and shear stresses are measured in order to investigate the separation of a quasi two-dimensional, oscillating boundary layer. The boundary layer separation occurring on the inclined prolate spheroid is examined by means of similar experimental techniques, supplemented by velocity measurements in boundary layers and in the vortex flow. The emphasis in the following sections is on the presentation of the experimental facts applying different measuring techniques and on the description of two-dimensional, as well as three-dimensional, separation phenomena.
