| 中文摘要: |
| 采用VOF法对挑流消能从库区到下游水垫塘进行了全程水气二相流二维数值模拟。模拟了射流的空中轨迹线和水垫塘的自由水面，得到了计算域的流线、压力、流场、紊动能k及紊动能耗散率ε分布，并用物理模型对模拟结果进行了验证，二者吻合良好。说明利用湍流二相流模型及VOF法对空中射流水舌及水垫塘流态模拟是可行的。 |
| 英文摘要: |
| The VOF method is applied to simulate the whole flow field of two-phase jet flow from flip bucket to plung pool. The free surfaces of projectile jet and plunge pool are simulated and the distribution of streamline, pressure, velocity, turbulent kinetic energy and turbulent dissipation rate in the computation domain are obtained.The simulated result is verified by model test data. Good agreement is attained. |
