Methods Employed to Remedy Water-Hammer Shock in Pumping Systems
Journal of Fluids Engineering, 1939Abstract This paper gives certain typical problems which have been encountered in English practice in pumping-plant installations, where surge conditions have been encountered, and the changes made to remedy them. The severity of the conditions and the effectiveness of the remedies are shown by pressure-recorder charts showing the line ...

Study of the Phenomenon of Water Hammer Based on Sliding Mesh Method
Applied Mechanics and Materials, 2014The 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.

As the needs for solving water quality deterioration in water supply network increased, more attention has been paid to effective pipeline cleaning technologies. Amongst them, water-hammer method and barometric-pulse method have the potential of scouring and removing the “growth-ring,” which is the main reason for the secondary pollution as well as the

The Method of Characteristics Applied to the Sensitivity Analysis for Water Hammer Problems
2021Water hammer is a transient situation in pipe flows that is created by a sudden change in velocity. This phenomenon can create large pressure fluctuations in pipes and often can present hazards in pipelines. Generally, water hammer is created by rapidly closing valves and by suddenly shutting off or starting pumps.
