| 摘 要： | 文章阐述了弯道横向环流的形成机理,建立了180°矩形断面弯道的概化模型,据此来分析弯道水流环流的流态特征。根据环流强度在不同剖面的沿垂线分布情况和等值线图,分析了弯道环流强度。通过流场在弯道各种断面的情况,得出的弯道环流特性可为相关的理论研究及工程实践提供理论基础。

| Abstract: | The formation mechanism of circumfluence was expounded in this paper,and the generalized model of a 180° rectangular section in curved channel was established to analyze the characteristics of fluid state. According to the vertical distribution and the isopleth map in different profiles, circulation intensity of the curved channel can be analyzed.With the help of the flow field in any section of the bend,the characteristics of circumfluence were obtained.These results may provide a theoretical basis for the theoretic research and engineering practice. |
