Finite Element Analysis for Water Hammer Problems in Pipeline Systems

The safety analysis of the nuclear power plants requires to assess the consequence of a hypothetical Loss Of Coolant Accident (LOCA) occurring in the primary circuit. Pipe rupture causes of water hammer, that is made the transient vibration of pipe systems. Water hammer as a transient phenomenon in liquid-filled pipe systems is considered. In this present work. A finite element formulation (Galerkin Method) for the coupled dynamic equations of motion to include the effect of fluid-structure interaction (FSI) as water hammer mathematical formulation, is introduced and applied to a pipeline system used in nuclear reactors. This method is validated by comparison with the references.
