Auscultation of the Corrigan or Water-Hammer Pulse
New England Journal of Medicine, 1952THE Corrigan or water-hammer pulse and the pistol-shot sound in the groin are time-honored physical signs of marked aortic insufficiency.

On the Fundamental Equations of Water Hammer
Urban Water Journal, 2004 The wide spectrum of practical problems that warrant water-hammer modelling has increased the importance of careful formulation of the fundamental equations of water hammer and critical analysis of their assumptions.

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.

Prevention of Water Hammer and Cavitational Hammer in Pipeline Systems
Chemical Engineering & Technology, 2002A new method for preventing water hammer and cavitational hammer in pipeline systems by an adaptive control of the valve closing process has been developed. To this end, the shut-off valve has been equipped with an innovative hydraulic brake system that acts onto the rotation axis of the valve and combined with a swing check valve. The described system

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.

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.

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 ...

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 ...

Journal of the Hydraulics Division, 1969
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.
