Water hammer is a type of transient flow in pipelines which may in general be produced due to valve closure or sudden shut down of pumps. Transient flow creates sudden variation in the velocity and pressure of fluid flow in the pipelines which in effect may induce some dynamic vibrations in the structure of pipe. Furthermore, such structural vibrations can affect the fluid flow. Taking into account them is necessary for modeling of fluid-structure interaction. In this paper the fluid-structural interaction (FSI) of water hammer in pipeline systems are investigated. Two sets of hydraulic and structural equations with common variables have been numerically analyzed through MOC-FDM simultaneous solving process which has been prepared by a computer-assisted program. Some examples have been solved by this method, with satisfactory results. This indicates that fluid-structure interaction can have critical effect on the value of fluid pressure.
