Dynamic characterization of water hammer in gangue fly ash slurry pipelines during valve closure

Scientific Reports
In the process of coal-filling mining, the gangue fly-ash slurry (GFS) needs to be transported over a long distance to reach the gobs. The abrupt closure of the valve during the transportation of GFS can result in a water hammer that significantly ...
