| 摘 要： | 采用RNGK-ε湍流模型与VOF多相模型对扭曲型挑坎挑流进行水气两相流三维数值模拟,模拟了挑坎里的自由水面与挑流的空中轨迹线,得到计算域的速度、压强、湍动能K与湍动能耗散率ε的分布、内外挑距与水舌宽度,并与物理模型的试验结果进行比较,两者吻合良好,验证了该数值模拟方法的可靠性、合理性。

| Abstract: | The RNG K-ε turbulent model and VOF multi-phase model were applied to simulate the water-air two-phase jet flow from a contorted jet bucket to a plunge pool.The free surfaces of the contorted jet bucket and jet trajectory were simulated,and the jet trajectory length and nappe width as well as the distribution of velocity,pressure,turbulent kinetic energy K and turbulent dissipation rate ε in the computation domain were obtained.Comparison with the model tests shows that the simulated results are in good accordance with the test data,and the numerical simulation method in this paper is highly reliable and rational. |
