Abstract

The interaction of shock wave with granulated layer of spherical particles was experimentally investigated in the atmospheric shock tube. There was a gap between porous layer and the end wall of tube. Two different cases were considered. In the first the structure and position of porous layer remained unchanged. In the second case, after the impact of the incident shock wave on the granular layer, the structure was destroyed and it turned into a moving particle cloud. For both cases, wave structures that occur both in front of porous layer of granular particles and in the gap between the layer and the end wall of the shock tube are obtained and analyzed.
