摘要
弯道环流是影响断面流速和含沙量分布的重要因素。本文提出了通过求解立面二维弯道环流运动的方法,在平面二维水流泥沙数学模型中考虑弯道环流的作用。该方法适用范围广,增加计算工作量不太大。
The secondary flow in river bends has significant effects on flow velocity and sediment concentration distribution in the transverse direction. By simulating a vertical 2-D secondary bend flow, the secondary flow effects were taken into account and the simulation was coupled with a planar 2-D depth-averaged model. The computational results showed that this method was widely applicable and the additional needed calculation work was limited.
