消力池消能效果影响因素的研究

The Study of Factors of the Energy Dissipation of Stilling Basin

通过VOF(volume of fluid)方法,模拟了水闸泄水时消力池内的流场情况。通过慈溪龙山排涝出海闸工程实例对模型精确性进行校核,在此基础上对消能效果的因素进行了研究。结果表明增加消力坎角度、消力坎高度和泄水水头高度可以增大消能率;结论可为低水头泄水工程的设计提供依据与参考。

The VOF（ volume of fluid） method is used to simulate the flow field of stilling basin in the sluices drainage process. Taking Cixi Longshan drainage sluice for example,the accuracy of the model is verified. Then the factors of the energy dissipation are studied. The results show that the ratio of energy dissipation increases with the increase of the baffle wall angle,height,and discharge water head height. The conclusion can provide scientific and effective theoretical support and reference for the project design.
