Numerical Simulation of Supercavity Shape Design of High-Speed Projectile

Abstract:

In order to investigate the drag characteristics of high speed projectile in the states of supercavitation shape, this article presents the shape design’s method and gist of the underwater high-speed projectile. The first, the shape model is presented that is based on the potential panel method to the slender axisymmetric body. The second, the effect is analyzed comparatively that is from the difference shape to the supercavitation. The simulation results show that smaller drag coefficient of the projectile can be obtained by increasing the slenderness ratio and the barycenter position.
