When the propagating shock wave reaches at the open-end of a tube, the impulsive wave discharges to the surrounding area. A new technique of passive control that augments the magnitude of an impulsive wave is proposed in this study. Experimental and numerical studies are carried out to examine the effects of new technique of the passive control that alter the exit geometry of a straigit tube to a flare and a cup. The effects of geometry parameter of a flare and a cup at the tube exit on the magnitude of the impulsive wave were investigated over the range of Ms from 1.01 to 1.1. The results were compared with those of the straight tube and showed that the present technique of passive control enable augment the magnitude of the impulsive wave.
