  • The interaction of a shock wave with a spherical gaseous interface (soap bubble) was observed directly by a high-speed camera. To trace the picture of the interface, white droplets were used to dye the test gas inside the bubble. Light gas bubble and heavy gas bubble under weak planar shock waves loading were studied. The geometrical characteristics of bubble evolution were obtained, and the ring-shaped structure in the light gas bubble was observed for the first time. We also analyzed the distribution of the displacement for the light gas bubble with the correlation method. The results agree quite well with the theoretical analysis. The successful usage of droplets encourages the introduction of more accurate diagnostic system like planar laser induced fluorescence (PLIF) or particle image velocimetry (PIV) into experiments in the future.
