Abstract

A simple configuration for a supercavitation vehicle propelled by water ramjet was proposed. Based on Reynolds averaged N-S equations, mixture multiphase model, and full cavitation model, the numerical simulation method for the internal and external flow field of the supercavitation vehicle was established. Based on this model, the flow field of a supercavitation vehicle with different configure parameters and sailing speed were simulated. Through analyzing the simulation results, the relation function between sailing speed, inlet diameter of water pipe, throat diameter of water pipe and the vehicle performance of drag reduction and water ingestion were obtained. Furthermore, the range and velocity variation law were calculated for a supercavitation vehicle launched at certain muzzle velocity. The conclusions have some instructional significance in the development of supercavitation vehicles.

Key words： supercavitation vehicle; water ramjet; water pipe; internal and external flow field; Mixture; numerical simulation
