[Abstract]:The initial underwater operation of the gas generator with an equal-pressure cavity is a complicated high-pressure drainage process, which rapidly experiences several states, such as supercritical and sub-critical, which is different from normal working state, which seriously affects the system's bearing capacity and the combustion of the charge column. In order to study the characteristics and effects of the process, a simulation method for the whole process is established based on the theory and CFD calculation. The simulation method is verified by a specific system test, and the general model of underwater ventilation drainage process is analyzed. The influence of typical parameters on the initial drainage process is studied. The results show that the system pressure is greatly increased during the initial drainage process of the gas generator with a uniform pressure chamber, and the working state can be improved effectively by adjusting the volume of the pressure equal chamber, the ratio of water filling and the diameter of the drainage hole.
