    Abstract
  • A homo-equilibrium model was used to compute the hydrodynamic cavitation flow field over an axisymmetric projectile by solving the incompressible Navier-Stokes equations. The governing equations were resolved in a finite volume manner, the convective fluxes were treated by an upwind differencing scheme and the time was integrated using the LU-SGS approach. A mass transfer model introduced by Kunz was implemented in a viscous Navier-Stokes solver. A preconditioning method was used for the low-speed computations and the point implicit method for the mass transfer source terms. The computations were performed for the cavitation flow of an axisymmetric projectile under the Reynold number of 136000 and the cavitation number of 0.1, 0.2 and 0.3. The wall pressure coefficients on the axisymmetric projectile were obtained and compared with experimental data, the agreements were excellent. And then, the super-cavitation phenomena were studied for σ＝0.2,0.1, 0.06, and the super-cavitation flow-field was obtained for cavitation number σ＝0.06.
