Abstract

A water hammer phenomenon due to sudden closure of a valve, with centrifugal pump at upstream, was studied both experimentally and numerically. Taking into consideration the fluid-structure interaction, it produced a four equations model (fluid continuity, fluid momentum, and pipe wall momentum and stress strain equations). The four equations model was analytically solved using the method of characteristics to clarify, the centrifugal pump effect on the hammering waves. A FORTRAN program was developed to solve the model. The theoretical and experimental results indicated the pressure-time history at different positions along the pipe for different valve closing times. Also, predictions for stress-time history, fluid velocity-time history and structure velocity-time history were obtained at different positions along the pipe at different valve closing times. The obtained predictions are useful in pipeline design.
