This paper reports the performance and flow characteristics of the shock tube equipped ,with a shock wave valve, which is modified in more feasible fashion for practical use from one previously proposed by Muirhead et al. In order to clarify the starting processes of the multiple nozzles, an experiment was conducted by means of this shock tube to observe the feature of the flow accompanying with the shock waves reflected from and passing through the multiple-orifice plate set normal to the flow at the test section.
