Abstract

Abstract

Vehicle exiting-water process is very complicated, accompanied by multiphase flow, cavitation, phase transition and turbulence instability, and the applied force is highly unsteady and nonlinear. Mostly, studies of vehicle exiting-water with cavitation focus on the vertical or oblique exiting-water internationally, and is focus on the trajectory and attitude of the vehicle.There are few studies on the exiting-water process of the supercavitation vehicle. In this paper, based on STAR-CCM+ software, overlapping grid technology is used to for meshing, VOF model is used to capture the gas-liquid interface, Schnerr-Sauer model describes the cavitation process around the vehicle, and a numerical calculation model of the exiting-water process is established. The flow field and cavitation evolution laws under different conditions that includes initial velocity, initial water depth and ventilate mass flow are obtained, and the hydrodynamic and kinematic characteristics of the supercavitating vehicle are analyzed. The simulation results show that the underwater motion of the vehicle with different initial motion velocity presents two different modes. Under different water depths, the initial cavitation number is different. Cavitation around the vehicle is more likely to rupture in deeper waters. The cavitation morphology can be improved effectively by increasing the ventilation flow rate.
