| 摘 要： | 研究了明渠结合有压管调水系统水力瞬变的数值模拟，采用明渠非恒定流基本方程同时描述明渠的非恒定流和管道的有压汉，对有压流动采用了窄缝法求解，此外，研究了用非恒定流计算方法求解恒定流动，并提出了保证数值计算收敛的措施和方法，作为应用，模拟计算了正在修建的东深供水改造工程的恒定流和水力瞬为流。

| Abstract: | Simulation of the hydraulic transients in the water diversion systems with open channels and pressurized pipelines is studied.The basic equations of one-dimensional unsteady flow are also used to simulate the hydraulic transients in pressurized pipelines.Moreover,it is also studied that a steady flow is solved as an unsteady flow is.At last,these methods are applied to simulate the steady flow and the hydraulic transients in the Dong-Shen Water Diversion Project. |
