摘要
利用三维水流数值模型对单向流下导流叶片对流场的影响情况进行了模拟与分析可知,计算值与实测值吻合较好,结果表明本文采用的模型能较好地解决复杂的紊流场;并通过水槽水平切面流场的分析可知在导流叶片附近存在一个逆时针漩涡,这个漩涡是造成导流叶片附近泥沙发生局部冲刷的主要原因。
In the paper three dimensional numerical models to simulate current near submerged vane was peformed. It shows that the results of calculation are in good agreement with the results of experimental measurements; by analyzing flow field of the flume, there is a anticlockwise eddy near submerged vane. The eddy is main cause of local scour near submerged vane＇s sediment.
