Abstract: 

In this study, significant features of supercavitation including formation, evolution and their effects on drag reduction for an underwater moving body are both experimentally and numerically investigated. To simulate the flow field of the underwater moving body, the multiphase Reynolds averaged Navier–Stokes equations (RANS) are coupled to a six-degree-of-freedom (6DOF) rigid body motion model. Due to the lack of high-speed underwater projectile experimental results, first, the lower-speed unsteady numerical simulation of the projectile with velocity 100 m/sec has been carried out and compared with the experimental data for tuning the available code. Then, the numerical simulation has been taken place for the high-speed underwater projectile with velocity 200 m/sec using the adjusted numerical algorithm. The experiments were performed for a spherical-nose projectile at Shiraz MUT Hydrodynamics Laboratory Cavitation Tank, and the projectile trajectory was recorded with a high-speed camera. Numerical results show that the supercavitation around the high speed projectile generates at less than 2 msec and drag force is reduced by 66%.
