| 摘 要： | 针对大单宽流量导流明渠体型优化难度高,下游消能防冲设计困难,物理模型难以详细测量水流流态和冲刷特性等主要问题,采用紊流数学模型方法对不同体型明渠水流流动和下游天然河道流场进行了3维数值模拟.结果表明,计算值与试验值吻合良好.通过对比3种体型下明渠的流速分布特性和冲刷特性,获得了模型试验难以测量的流场详细信息,为明渠的体型优化提供了重要参考.研究表明,将数值模拟技术应用于导流明渠的体型优化研究中具有独特优势. |

| Abstract: | In order to overcome the problem that the physical model is difficult to measure flow forms and scouring characteristics in great unit discharge diversion channel, the turbulence model was used to calculate diversion channel flows and natural river flows. The results showed that the calculated values were in accordance with the experimental data. By comparing three types of velocity distribution characteristics under diversion channel, the flow field details was obtained. |
