Essential Features and Numerical Modelling of Bend Flow

Dong Yaohua(Yangtze River Scientific Research Institute, Wuhan 430010)  
The essential features of bend flow, including lateral slope of water surface, lateral circulation flow, redistribution of velocity, disaffiliating flow, bend shear stress and bend local head losses, etc., and their present research situation, are summaried. A 2-D depth-average mathematical model of bend flow under polar coordinates was established. By using this model, the calculation of two examples was conducted, i. e., the 180°rectangle bend channel model flow and the Tiaoguan curved river reach of Yangtze River in prototype. The calculated results show that the established mathematical model can satisfactorily simulate the variation of water surface pattern and redistribution of velocity in bend flow.
