摘要
在管网系统的运行操作中,阀门误关闭、管道堵塞、停泵等都会导致流体的瞬变流动,由此产生的水击压力波可能导致管段的强度破坏。环网的瞬交流动计算问题较为复杂,需要求解高阶非线性方程组,对于复杂的网状结构,系统的自动识别或标记相当麻烦。通过对环网系统水击问题的分析研究,提出了求解任意液体环网问题的计算方法和相应的计算程序。
In the operation of a ring pipe network system, many factors, including misplaying valves, jamming pipes and shutting down pumps, may trigger the transient flow. Subsequently, the water hammer pressure can cause intensity breakage of piping. The calculation of the system is complex, because of solving high haw equation group. It is also a trouble to sign and identify for the equation group. To be aimed at the water hammer problem in a ring pipe network system, the mathematics model and numerical method of transient flow are proposed. The software simulating the transient flow course in a fluid ring pipe network is programmed.
