Simulation and Analysis of Water Hammer Effect in Water Pipeline

Abstract

Due to the fast conveying speed of water or other liquids, when the valve is suddenly opened or closed, it is easy to present water hammer effect. The existence of water hammer problem can easily lead to accidents such as pipeline bursting or pipeline collapse, which not only affects the safety of the transportation process, but also interferes with normal production causing economic losses. This paper will analyze the principle of water hammer effect and determine the wave speed of water hammer by solving the basic differential equation of water hammer and combining the calculation results. Use SOLIDWORKS software to establish models of water pipelines and valves, and use FLUENT software to simulate and simulate the water pipelines and valves. Through two observation points, the changes in the pressure and fluid flow rate in the water pipeline are observed to analyze the effect of water hammer on the water pipeline.
