| Abstract: | To study the compressible effect of water on the supercavity profile when the velocity of an underwater body was close to the sonic speed in water,the ideal compressible steady supercavitating flow over the disk cavitator was numerically simulated based on the finite volume method and the potential theory.Supercavity was closed by Riabouchinsky model.Water compressibility was taken into consideration by using Tait state equation.A new iteration method for the supercavity shape updating was proposed and the ... |
