| 摘 要： | 为了优化U形渠道直型式量水槽水力计算,由U形渠道直壁式量水槽模型试验得出的水力特性基础上,对量水槽的部分工况进行数值模拟,得出了水位与流量的关线曲线.试验结果表明,自由水面线的计算与实测值符合较好,流速分布规律揭示的水流特性与实际状况相符,所选模型能够准确模拟量水槽的三维水流特性,该数值模拟方法可靠,为量水槽的优化设计提供了思路.

| Abstract: | Based on the hydraulic characteristics obtained from model tests of U-shaped channel straight wall measuring flume,some working conditions of the flume were simulated and the discharge rating curve was calcuated.In order to optimze the hydraulic calculation of U-shaped channel straight wall measuring flume.The results show that the calculated values of piezometric line correspond with the measured values,and the flow characteristics shown from velocity distribution pattern are consistent with the practical conditions.The chosen model can simulate correctly 3D flow characteristics of measuring flume and the numerical simulation method is reliable.It provides a guideline for optimal design of measuring fume. |
