    Abstract
  • In order to investigate the characteristics of ultra high speed torpedo (UHST) ventilation system and obtain solutions of mass flow rate allocation in specified proportion, we computed the flow flied with the CFD software FLUENT based on the compressible gas-water multiphase flow model. The flow field was simulated using a 2D axisymmetric mesh, and the contours of gas volume fraction, pressure, temperature and Mach number were achieved. By analyzing the characteristics of the flow field, a scheme for designing the sizes of ventilation holes was presented to realize the allocation of mass flow rate in specified proportion. The result has been applied to design a ventilation system, and the test verified the present scheme.
