Unsteady Supercavitating Flow on Cone Cavitator

Based on an integral equation method,the unsteady supercavitating flow past slender body was studied.The shape and length of supercavity was calculated respectively using a finite difference time discretization method.The characteristics of the shape and length of supercavity varying with the cone's angle and cavitation number were investigated respectively.It obviously shows that supercavity's change has retardancy and waviness.
