Water hammer analysis in main pipeline of water treatment plant for the Bakhma residents

Abstract EN

A numerical model using approximate method of characteristics has been presented for solution of the transient flow situations of water hammer and application on a main pipeline joining the intake and water treatment plant for the residents in Bakhma Dam.

This case study demonstrates the capability to simulate the water hammer effect by simulating the sudden closure of a valve at the outlet of a long pipe in which water is flowing.

The case study includes three pipelines (reaches) of the same diameter and different length and static pressures.

The objective of the simulation is to investigate the pressure variation at different positions along the length of the pipe due to the water hammer effect resulting from the sudden closure of the outlet of the pipe.
