| Abstract: | Based on the 6DOF dynamic mesh and overlapping mesh technology in Fluent software, the numerical simulation of the projectile entering water at different angles is carried out, and the influence of the projectile entering water angle on the supercavitation characteristics of the projectile is studied. The simulation results show that the morphology of the cavitation on both sides of the projectile is asymmetrical, and the size of the cavitation on the right side is smaller than that on the left side. When the entry angle of projectile is 15°, the fluctuation range of yaw angle and roll angle is smaller.When the relative angle of entry is 5°, its water entry stability is better. The water entry angle has very little influence on the roll moment, yaw moment and pitch moment in the stable phase of projectile flow, and the pitch moment increases continuously after entering the water. |
