| 摘 要： | 采用数值模拟的研究方法，以溢洪道为研究对象，分别采用标准k-ε模型与RNG k-ε模型，对溢洪道进行二维水气两相流数值模拟，通过与物理模型试验数据相对比，探究不同计算模型对溢洪道数值模拟计算所得数据的准确性。经验证标准k-ε模型计算所得结果较为准确，且耗时较短。

| Abstract: | The paper utilizes numerical simulation research method and makes spillway as the object of the study.It respectively adopts standard k-εmodel and RNG k-εmodel to numerically simulate the air-water two-phase flows of the spillway,and explores the accuracy of the data that all different calculation models bring via comparing with the physical model test data.The test verifies that the results of standard k-εmodel tend to be more accurate and it spend shorter time as well. |
