Experimental study on parameters of water particles in the cloud from liquid film induced by shock wave
摘要
Abstract
Cloud of liquid film induced by shock wave was observed and investigated by phase Doppler particle analyzer system, and related parameters of diameter and velocities were obtained. The results indicate that liquid film of various thickness induced by the shock wave of the same intensity produced water particles with strikingly different vertical velocities and slightly different horizontal velocities. The size of the cloud, the vertical velocity and size of the droplets show an inverted "W" shape. Through a sorting-out and analysis of the test results, the aerodynamic force is the main force in the initial time period after the reaction of shock wave while the weight of droplet and the frictional resistance in the air play a key role with the increase of dispersion distance. Thinner water film means stronger transmitted wave, the dispersion scope becomes wider. The diameter of cloud becomes bigger because of larger horizontal velocity.关键词
