Study of the Phenomenon of Water Hammer Based on Sliding Mesh Method

Abstract:

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 water hammer phenomenon caused by the sudden closing of the valve and it is closer to the experimental results compared with the traditional method of characteristics.
