Fundamental studies of shock wave-boundary layer interactions in a three-dimensional channel
Abstract
A summary is presented of the existing ONERA database and flow visualization capabilities for shock wave-boundary layer interactions. Attention is focused on trials performed with fixed airfoils in a convergent-divergent transonic wind tunnel. The flows have been scanned in three directions with LDV (6000 samples/sec) and high speed photography, and pressure taps have collected data along the wall. Among the findings has been the formation of two separation regions, one on the upper wall, where the foot of the shock wave appears. Several sample visualization images and calculated velocity profiles are provided.
