Abstract
Numerical results of the flowfield with shock/vortex interaction are presented. A shock wave is exhausted from an open end of a shock tube, followed by vortex rings. The shock wave is reflected from a plane wall which is placed perpendicularly to the axis of the shock propagation at a certain distance from the open end of the shock tube. The vortex ring interacts. with the reflected shock wave and then it approaches the wall. According to the numerical results, when the vortex ring comes close to the wall, a wall vortex is induced and a new shocklet is generated between the vortex core and the newly induced wall vortex. It has been clarified that the mechanism of this shocklet is the same as that in a supersonic nozzle.
