Study of the Phenomenon of Water Hammer Based on Sliding ...
The sliding mesh method of Fluent was used to simulate the dynamic course of ball valve closure. The pressure before the valve was calculated both at constant density and variable density and compared with that of the experiment and the method of characteristic. The results show that when considering the compressibility of water, Fluent can be used to simulate the pipeline .

The Water Hammer phenomenon: A look at the cause and effect
Water Hammer: A look at the cause and effect Water hammer is a hydraulic phenomenon that occurs when flowing water is abruptly stopped by a block in its path. Since water molecules have very limited compression capability, a sudden stop forces the water to move in the opposite direction, which is again slammed forward by incoming water and so on.
