Water Hammer: Pressure Wave Propagation in Pipes

This information video shows the CFD simulation of an interesting physical phenomenon: the pressure wave propagation in pipes or in other words the water hammer effect. There are two examples shown in the video. The first is a simple pipe, the second one is a bit more complex because there are junctions in the pipeline which have important effect on the pressure wave.

This application example was one of the firsts I uploaded to YouTube, almost 9 years ago, It’s been quite a while now but still interesting for those who are looking at simulating pressure wave propagation aka. water hammer in pipe systems.

The CFD code I used for this case study was CFdesign (not available any more), but any other CFD code can do analyses like this that are capable of running compressible liquid simulations.
