Effect of pipematerials on water hammer
International Journal of Pressure Vessels and Piping, 2020Abstract Water hammer is a transient flow in pipes that were made by quickly change in speed in pipes. This phenomenon can cause genuine positive and negative pressures in pipes and frequently with hazards in pipelines. Generally, water hammer makes by closing valves quickly and has one of the most dangerous hydrodynamic phenomena in pressurized ...

Why Concept Water Hammer? We have a range of hydraulic concepts but as a poor cousin of hydrology it is often regarded as an exercise in Bernoulli and little else. Water hammer seldom gets suitable treatment which is neglectful, since in physical structures dynamic loads are not regarded lightly as most building codes will show.

Numerical Calculation of Water Hammer
2023In this chapter, the Method of Characteristics (MOC) is detailed and used to solve the mathematical models defined in the second chapter, where the reservoirpipe-valve-system is considered. The wave-speed adjustment (WSA) scheme is preferred for the MOC.

User-interfaces based on the water-hammer effect
Proceedings of the fifth international conference on Tangible, embedded, and embodied interaction, 2010Water hammer, a well known phenomenon occurring in water pipes and plumbing fixtures, is generally considered destructive and undesirable. We propose the use of water hammer for a musical instrument akin to hammered percussion instruments like hammered dulcimer, piano, etc.

Simplified methods of calculating hydraulic transients are set forth, with techniques for increasing the computing time interval over that permitted by the characteristics method. Lumping and interpolation methods are compared with mixed implicit and characteristics methods.

Water Hammer in a Liquid with Gas Bubbles
International Applied Mechanics, 2001The author considers a semi-infinite rigid pipeline with the starting point at the cross-section \(x=0\) (the axis \(OX\) is directed towards the flow of liquid with bubbles). It is assumed that at the cross-section \(x=0\) the law of changing the mixture flow is prescribed.

Viscous Dispersion in Water Hammer
Journal of Basic Engineering, 1960When a column of fluid moving with uniform velocity is instantaneously stopped at the downstream end a pressure wave is propagated upstream. In an inviscid fluid the wave is a step discontinuity, and the pressure so calculated serves as an easily obtained upper bound for all practical “water-hammer” problems, the exact solution of which may be either ...

Water hammer is still a "bugbear" to water works men. It seems to be forever with us in causing breakage and leaks in the distribution system. It is of concern to the superintendent because his service of supply is closely allied with the work of architects, engineers, and plumbers in making satisfactory distribution systems in buildings.
