Abstract

Abstract

An experimental investigation of Richtmyer-Meshkov (R-M) instability in the elliptic heavy gas cylinder was presented in detail. The shock-induced instability was studied in a horizontal shock tube using the planar laser-induced fluorescence (PLIF). The gas cylinder surrounded by air was composed of SF₆ and acetone vapor. By adjusting the ratio of the long axis to the short one in the gas cylinder was achieved the evolution of three types of initial interface accelerated by a Mach 1.25 shock. After the calibration, concentration map were obtained. Furthermore, the congregation, transfer and dissipation in the concentration field was revealed. With a larger aspect ratio, the gas cylinder has a wider deposition of baroclinic vorticity, resulting in a faster evolution. When the evolution is rapid, a jet occurs in the trail structure due to the collision of the vortex pair. It was demonstrated that the initial configuration directly determines the strength and spacing distance of the vortex pair at early times, thereby exerting a significant influence on the instability evolution at later times.
