Resistance Characteristics of Underwater Supercavity

Abstract:

This paper based on the Homogeneous equilibrium multiphase flow theory.By using FLUENT software the high-speed underwater projectile resistance characteristics were studied.Analyzed the influence of cavitator diameter and Cavitation number on drag reduction characteristics of the projectile,and compared with the empirical formula.The results showed that the larger the diameter of cavitation,the easier supercavitation natural formation,but the drag coefficient be greater.
