| Abstract: | The RNG turbulent model and VOF multiphase model were applied to simulate the water-air two phase jet flow from a contorted&beveled jet bucket to a plunge pool. The shape of tongue, horizontal length and height were simulated, and the distribution of velocity, turbulent kinetic energy and turbulent dissipation rate in the computation domain were obtained. Comparison with the model tests showed that the simulated results were in good accordance with the test data, and the numerical simulation method in this paper was highly reliable and rational. Furthermore, it also can provide some data for engineering design. |
