Experiments on Compressible Vortex Ring Interaction with a Cone Mounted on a Flat Plate
摘要
When it comes to compressible flows, the formation and development of the vortex ring are of paramount importance, such as starting the rocket nozzles, volcanic outbursts, etc. In this paper, the shadowgraphy flow visualization method has been adapted to find out the behaviour of the flow coming out of an open shock tube interacting with a cone mounted on the flat plate. The impingement of compressible vortex ring with cone and plate validates some new flow features and structures, like formation of tent shock and, instability in jet due to interaction of reflected shock observed in simulations.
