A study of processes occurring in a compressed layer during the collision of a fluid droplet with a moving body
Abstract
The processes taking place in gas flow following the collision between a fluid droplet and a body moving at a supersonic velocity are investigated experimentally using a sphere of 30-mm diameter moving in air at 650 m/s and colliding with a 3-mm-diameter droplet of water. It is shown that the droplet-body collision gives rise to two shock waves in the gas which move behind the head shock. The first shock wave is excited due to the dispersion of the droplet decomposition products at velocities exceeding the local sound velocity; the second shock wave is excited as a result of the formation of a rarefaction region due to the dispersion of the liquid.
