文摘In the presellt work, The three-dimensional turbulent particulate-liquid two-phase flows have been simulated through a hydraulic nancis turbine runner by using the turbulence model and the SIMPLEC algorithm on the bases of the theory of two-fluids model for multiphase flows. In this theory, the particle phase at dilute conceniration conditions, is assumed to be a pseudo-fluid and occupies a certain fraction volume in the whole flow domain shared with the colltinuum phase, i.e., the real fluid phase. Velocity distributions of the two phases through the runner are indicated in this paper as calculated results.
