    Abstract
  • Ventilated supercavitating flow involves such topics in fluid mechanics as multiphase flow, turbulence, phase change and compressibility, its mechanism is very complex. The multiphase flow model has attracted much more atten-tion in the study of numerical simulation of supercavitating flow, however its accuracy in simulation is not satisfactory. In this paper, the homogeneous model, which are widely used in the world, are compared with the Euler two-fluid model by combining with the authors′ research by means of water tunnel experiments and numerical simulation. The advan-tages of the Euler two-fluid model in predicting ventilated supercavitation is analyzed in terms of cavity shape and hy-drodynamics of a vehicle. Numerical simulation of ventilated supercavitation is expected to become an important ap-proach of drag-reduction technology through supercavitation.
