Study on cavitation flows of underwater vehicle

In this paper, numerical simulation was utilized to deal with the cavity generated at the tip and surface of vehicle. As for the water flow field of cavitation, the two-dimension axial symmetric Hess-Smith method, which was based on the potential theory and panel technique, was employed to deal with the problem. And surface pressure coefficient and drag character of cavity at axial symmetric body were analyzed. The tip drag of cavitators with different dimensions were also computed and discussed.
