Segmented Pipeline Test Rig
Warning: This example uses the hydraulic domain, which will be removed in a future release. Find an equivalent example model that uses the isothermal liquid domain here: Water Hammer Effect. To convert models to the isothermal liquid domain, use the hydraulicToIsothermalLiquid tool.
This example shows a test rig used to investigate the water hammer effect, which occurs when a variable orifice is abruptly shut off with full flow rate flowing through the branch. The water hammer behavior of the pipeline can be investigated by changing pipeline dimensions, number of segments in the pipeline model, fluid properties, valve closure speed, and minimum opening.

Simulation Results from Simscape Logging
The plot below shows the pressure in each of the chambers in the segmented pipeline. The orifice at the outlet of the pipeline closes suddenly, creating pressure waves within the pipeline (water hammer effect).
