| 摘 要： | 借鉴有关弯道水流流速分布的研究成果,计入弯道环流引起的横向动量交换,对曲线坐标系平面二维浅水方程做了修正;采用边界处正交的曲线网格生成技术,处理复杂的计算区域边界。采用修正后的模型对田市抽水站进水前池改造前后的水流流态作模拟分析,来验证改造设计方案的合理性。

| Abstract: | According to the past research results about the bend flows,the modification of a horizontal 2D shallow water model in curvilinear coordinates is made considering the transverse momentum exchanges caused by secondary flows in channel bends,and the curvilinear coordinate system is generated by using the proposed boundary-fitted coordinate technology,with which a curvilinear grid being orthogonal near the boundaries can be obtained.By using the modified mathematical model,the behaviors of the flows through th... |
