Experimental investigation of breakup times of droplet under the action of shock wave

Abstract In this paper, the morphological characteristics and breakup time of droplet under action shock wave were investigated experimentally. Morphological captured by high-speed photography. By varying diameter droplets taking influence Mach number into consideration, eight tests performed in experiments. The experimental results showed that wave, underwent two different stages: deformation stage atomization stage. stage, evolved from spherical shape to pineal accompanying airflow induced wave. growth unstable on surface caused Rayleigh–Taylor instability was main reason for be atomized. effects initial analysed. decrease increase reduced time. played a dominant role process droplet.
