Abstract
An experimental study has been conducted to examine the interaction of a shock wave and a vortex ring with a at plate and a perforated plate. The experiments were carried out using a 30mm internal diameter shock-tube. The driver and driven gas was air. Highspeed Schlieren photography was employed to study the development of the o w-eld and the resulting interactions with the plates. Wall pressure measurements were also carried out to study the o w quantitatively at the exit of the shock-tube. Three dieren t driver pressures of 4, 8 and 12bar were examined under critical driver length conditions; the shock wave Mach number was 1.33, 1.52 and 1.67, respectively.
