Abstract

The study about supercavitating projectile is under water way at Shock Wave Research Center (SWRC), Tohoku University. Spherical and slender body projectiles are going to be launched into the water at velocity ranging from 1500m/s to 2000m/s. The motion of these projectiles was successfully visualized and analyzed. It is found that the drag force was smaller compared to the conventional results with single-phase flow.
