| Abstract: | In this paper a simple model is proposed to study the propulsion process of the hyperthermal gases in nozzle and the formation and evolution of the gas zone in water.The compressible Navier Stokes equations are also numerically solved using finite difference method.Our calculated results have verified that the simple model is reasonable to predict approximately the complex flowfield of the rocket launch under water. |
