Numerical simulation of water hammer in low pressurrized pipe: comparison of SimHydraulic and Lax-Wendroff method with experiment
Original language description
Article describes simulation of unsteady ?ow during water hammer with two programs, which use different numerical approaches to solve ordinary one dimensional dfferential equations describing the dynamics of hydraulic elements and pipes. First one is Matlab-Simulink-SimHydraulics, which is a commercial software developed to solve the dynamics of general hydraulic systems. It de?nes them with block elements. The other software is called HYDRA and it is based on the Lax-Wendrff numerical method, which serves as a tool to solve the momentum and continuity equations. This program was developed in Matlab by Brno University of Technology. Experimental measurements were performed on a simple test rig, which consists of an elastic pipe with strong damping connecting two reservoirs. Water hammer is induced with fast closing the valve. Physical properties of liquid and pipe elasticity parameters were considered in both simulations, which are in very good agreement and dfferences in comparison wi
