摘要
本文以河南水厂泵站引水工程为例,对待验证的梯形复式断面引水明渠流场特征进行模拟分析。结果表明:相比于工况1、工况2,工况3下的水流紊动特征最弱,明渠对口门区的冲击及破坏力也最小,对保障工程正常运行有利。
Taking the diversion project of pumping station of Henan water factory as an example, this paper carries out the simulation analysis of the flow field characteristics of the open diversion channel in trapezoidal compound section. The result shows that： the stream current turbulence characteristics of the work condition 3 is the weakest when compared with work condition 1 and work condition 2, and the impact and destructive force on the port gate area by the open channel are also minimum, which are beneficial to guarantee the normal operation of engineering.
