Paper Title:
Investigation of the Disk Cavitator Cavitating Flow Characteristics under Relatively High Cavitation Number
  Abstract

Simulations on two-phase cavitating flows containing water and vapor, on axisymmetric body with disk cavitator have been implemented through the cavitation model in Fluent 6.2, the flow field around cavitator under different incoming conditions is studied respectively, and analyses to parameters pertinent to cavity including dimension, streamlines, vapor volume fractions and pressure distributions along the body surface are given when the incoming cavitation number ranges from 0.3 to 0.8, the results show that the vapor volume fraction and threshold phase-change pressure within the cavity under the same cavitation number gradually ascends as the Reynolds number increases ; the effects of incoming pressure on threshold phase-change pressure inside the cavity is insignificant.
