U形渠道临界水深、弗劳德数和水跃的研究

摘要

提出了U形渠道临界水深、弗劳德数和水跃的计算方法.给出了U形渠道临界水深的迭代计算公式和弗劳德数的显式计算公式,推导出了U形渠道的水跃方程,与文献[7]的实测数据进行了对比分析,验证了公式的可靠性.%This paper presents the calculation method of the critical water depth ,Froude number and hydraulic jump of U-shaped channel. An iterative calculation formula for the critical water depth is proposed, an explicit formula of Froude number is given as well. And at the same time, the equation about the hydraulic jump of U-shaped channel is deduced. The comparative analysis is made of the measured data cited in reference(7) ,whereby testifying the equation reliability.
