The use of capillary as a sensor of cavitation

, 2002
The dramatic rise in height of the meniscus within a capillary, the other end of which is immersed in a liquid undergoing ultrasonic cavitation, represents a novel, robust and inexpensive method for monitoring cavitational activity.

Cavitation Reduction of Butterfly Valve by Flexible Fibers and Sheet Materials

, 2023
Butterfly valves are most commonly used in all industrial plants because of their simple construction. This cavitation phenomenon, which cannot be avoided in butterfly valves, is known to be caused by the interference of the flow from the front and rear ...

The monitoring of cavitation in centrifugal pumps based on the analysis of vibro-acoustic measurements

Cavitation in centrifugal pumps causes damages to pump components and produces high levels of vibration and noise, which not only reduces pump performance but also consumes additional energy.
