【Abstract】 Based on the transient flow theory of fluid dynamics, a numerical solution to the water hammer problem of water supply pipe networks was outlined by use of characteristic curve method and computer code has also been programmed. The power rule was utilized to treat fluid flow frictional resistance in the paper so that the numerical simulation could also be implemented if a pipe networks were used to transport other liquids of various behaviors. The code provides a useful tool for performing water hammer analysis of complex ring distribution system which includes pumps, reservoirs, water towers, multiple branch pipe joints and so on.更多还原
