Study On Numerical Simulation Of Water Hammer In Water Transfer System

This text mainly carries on research to Numerical Simulation Method of Water Hammer in Water Transfer System,first,the basic theory of water hammer and the derivation process of the solution named characteristic method of water hammer's equations are described,and calculate water hammer in simple pipeline with this method. A soft named AFT impulse is used to simulate the transient flow of the complex branching pipeline.Introduce the theory of gas liquid two phase transient flow,and to make numerical simulation with AFT,the accuracy of this soft and the flow coefficient of valve's influence on gas liquid two phase transient flow are verified by the result. This paper applies the structural drawing oriented simulation method to the simulation optimization of long-distance complex water conveyance systems,and studies to found a digital simulation model for water conveyance systems on the Matlab system simulation platform then make simulation study.
