Using five comparatively simple shape converging- diverging nozzles which have been installed in the low pressure side of a shock tube, the transient flows induced in the nozzles by the impinging of the shock front have been observed optically by the schlieren method. Moreover, the formation process of the reflected shock when the shock front impinges on the nozzle has been clarified. using two different nozzles with the same contraction ratio. As the result, the effects of the shape of nozzle and the incident shock Mach number on the formation process, and the formation distance of the reflected shock were found. And it was elucidated that the reflected shock strength was dependent on not only the contraction ratio but also the shape of the nozzle.
