导流板长度与放置角度对导流效果的影响分析

Analysis of Length and Placement Angle of Movable Diversion Vanes on Diversion Effect

文中选用汾河中游的河道参数,通过数值模拟计算分析了导流板长度和倾斜角度对导流效果的影响。研究结果表明:导流板可以改变水流的流向。导流板长度越大,水流受到的扰动越大;倾斜放置的导流板对水流的改变较缓,水流对导流板的冲力也较小,有利于导流板的稳定。

The effect of different length and placement angle on movable diversion vanes was studied by numerical simulation based on the parameters of midstream of the Fenhe River. It was shown that the vanes can change the flow direction of water, the greater the vane length, the greater the flow being disturbed; tilted vanes moderate changed the water flow, corresponding, the momentum of the flow on the vane was relatively small, and it was benefit to the stability of the vanes.
