    Abstract
  • The aim of this investigation is to research the initial ignition of the underwater-launching solid rocket motor. The MIXTURE multiple-phase model was set to simulate the initial ignition. The water vaporization was researched and the energy transfer was added to the energy equations. The flow field and the vaporization were calculated coupled. The initial ignition process of the underwater solid rocket motor is obtained and the vaporization influence to the underwater launching is analyzed. The "neck", "inverted jet" and "eruption" phenomenon of the bubble are observed. The bubble increases more rapidly because the steam mass added to the fuel. The temperature is lower considering the vaporization because the steam enthalpy is lower than the fuel enthalpy and the flow field of the initial ignition of the underwater-launching solid rocket motor is accordant well to the reference.
