Abstract:
      In this paper, a numerical two-phase flow model combining with the Realizable k-ε turbulent model for compressible viscous fluid was presented for the simulation of the flow around the fixed-cone valve. The equations were solved with the finite volume method. The free fluid surface was simulated by the VOF method. The function of the fixed-cone valve for energy dissipating was pointed out by analyzing the computed pressure field, velocity field and streamlines distribution. Compared with the experimental data, the simulating results show that the proposed model is reliable and can be applied to the numerical simulation of turbulence flow around the fixed-cone valve.
