Numerical Simulation of the Launching of Underwater Vehicle

Abstract:

The numerical simulation of multipahse flow characteristics during the launch process from the tube of the submarine vehicle are investigated, obtains the variation rules of the movement characteristic of the gas inside the tube, the cavity shape of around the vehicle body, the surface pressure coefficient during the movement process. The resluts show that the launch depth and velocity have significiant impact on the shouder cavitation of the submarine vehicle, the smaller values of the depth and the velocity are, the more obvious shouber cavitation, and which led to the distribution difference of the surface pressure coefficient
