摘要
对于一个水力稳定的管网系统,当其各管道的边界条件维持不变时,由于摩阻及水锤波的反射作用,管网内的任意非恒定流终将趋于其特殊情况──恒定流状态。基于这一原理,本文从管道非恒定流数值分析的特征线法出发提出了一种适用于复杂给水管网恒定流计算的新方法──特征线法。本文给出了该方法的数学模型.并通过算例验证了该模型的正确性和实用性。
With the boundary condition of all pipes in a pipe network kept unchanged,any unsteady now from arbitrarily initial condition in the network will approach its final steady state due to friction and waterhammer wave reflection.Based on this principle,a new alternative,the characteristic method is presented in this paper for calculating steady now in complex water supply systems.The mathematical model of the method is derived,and computational example are included,showing the correctness and applicability of the method.
