Abstract

The water entry of torpedo based on FE-SPH coupling method was studied. Firstly, the model of water entry of high-speed torpedo is established. In the case of grid structure, the numerical simulations verify the effectiveness of the model by comparing with the experimental results. Then the impact forces of the water entry about the torpedo were calculated with different entry angles and entry velocities. The results were compared with the results of FE method. The conclusions are expected to be beneficial to forecast the impact forces of water entry about the torpedo based on FE-SPH coupling method.
