Abstract: An experiment on the interaction of a compressible streamwise vortex with a moving shock wave has been conducted in a shock tube with 94 mm×94 mm square cross section. A finite span wing was mounted in upstream of the test section. When a shock wave passed through the wing, a streamwise vortex was induced from the tip of the wing by the supersonic flow behind the shock wave. After the incident shock wave reflected from the end of the shock tube, the interaction of the reflected shock wave with the strea...
