    Abstract
  • The influence of tail jet intensity on the steady supercavitating flow was analyzed, and a numerical investigation of the ventilated cavitation and tail jet flow field of a 2D underwater vehicle model was performed by using FLUENT. Several numerical simulation examples were given, and the simulation results indicate that when the flow velocity, environment pressure and ventilation condition remain unchanged, the geometrical shape of supercavity before it closes on the tail jet stream changes little with the increase in intensity of tail jet. The obtained law agrees with the results observed from the water tunnel test, which indicates the simulation model is valuable to engineering application and can be taken as a reference for designing hydrodynamic configuration of supercavitating vehicle.
