Membrane Fouling Mitigation with Water Hammer
… to mitigate fouling by subjecting a membrane to water hammer. The water hammer was generated by a solenoid valve installed at the retentate side of a cross-flow ultrafiltration unit. With this configuration, we hypothesize that the backpressure generated from the water hammer effect (WHE) could …

Water Hammer: An Analysis of Plumbing Systems, Intrusion, and Pump Operation
This thesis provides a comprehensive look at water hammer with an emphasis on home plumbing systems. The mathematics of water hammer are explained, including the momentum and continuity equations for conduits, system construction, and the four-point implicit finite difference scheme to numerically …

A study of the reflection and transmission of a water-hammer pressure wave from a tee
… and transmitted waves which were produced when a water-hammer pressure wave encountered a tee in the pipeline. The analysis included the fact that a hydraulic loss existed across the tee. Relationships were developed for determining the magnitude of the reflected and the transmitted waves. …

On axially symmetric elastic wave propagation in a fluid-filled cylindrical shell
The early stages of propagation of a water hammer disturbance are investigated, water hammer constituting a special case of axially symmetric elastic wave propagation in a fluid-filled cylindrical shell. Many of the objectionable features of the elementary (Joukowsky) water hammer theory are …
