Abstract

Water hammer phenomenon is a common problem for flows in pipes. Water hammer usually occurs when transfer of fluid is quickly started, stopped or is forced to make a rapid change in direction. The aim of this study is to use method of characteristics to study water hammer phenomenon. In this study, computational method is used to investigate the transient water hammer problem in a straight pipe. Method of characteristics is applied to constant density flow in a simple reservoir-pipeline-valve system. The water hammer effect is produced via suddenly closing the valve located at the upstream and downstream ends, respectively. Quasi steady shear stress is assumed for the flow. This study also considers steady and unsteady friction. Fluid structure interaction will also be analyzed. The results obtained show slightly higher pressure than that of published experimental data. This could be due to the Quasi steady shear stress assumption. Final results show that when fluid structure interaction is considered, more accurate answers were determined.
