Abstract
Body shape of high-speed underwater vehicles has a great effect on the supercavitation behaviour. The transit flow around either partially cavitating or supercavitating body affects the trajectory of high-speed underwater vehicles. Commercial code (ESI-CFD ACE+, V 2010) is used to simulate the supercavitation phenomenon. Cavity shape was determined over projectile body and around wake by high speed camera. This paper compares between the numerical simulation results for the flow of supercavitating on these different nose shapes and experimental results to verify the theoretical ones. Navier-Stokes equations were used as governing equations for simulating supercavitation. Grid designs are structured and unstructured grid. Also, two-dimensional flow field around the cavitating body was determined. Projectile body has a diameter about 0.4times its length (0.4L).
