| 摘 要： | 本文利用紊流模型模拟了带有曲线自由表面的宽顶堰流的紊流流场,采用VOF法来确定自由表面,采用气液两相流计算模型对宽顶堰流场进行了数值模拟,计算结果与试验数据较为吻合.模拟结果表明,数值模拟是作为研究水利工程中带有自由表面的水流结构的一个强有力的工具,其结果对物理试验也是一个很好的补充.

| Abstract: | This papaer introduces the turbulent flow field using turbulence model simulating the wire flow with a curve free surface,and VOF method used to determine the free surface,a two-phase flow model carried out simulating the weir flow field,which results and test data are more anastomose.The results show that the numerical simulation is very powerful tool to research hydraulic structure with a free surface and the results is a good supplement for physical tests. |
