Research on cavitation phenomena in pilot stage of jet pipe servo-valve with a rectangular nozzle based on large-eddy simulations

AIP Advances, 2019
The flow field in the pilot stage of a jet pipe servo-valve significantly affects the performance of the valve. Cavitation with pressure oscillations occur in the pilot stage and lead to the appearance of high-frequency noise and vibration.

Characteristics and Analysis of a Cavitation Jet Mixer [PDF]

Chemical and Petroleum Engineering, 2015
Operation of a mixer-ejector in the cavitation mode is investigated. An analytical expression for the dimensionless pressure-capacity curve of the cavitational mixer-ejector is derived. The limiting allowable characteristics permitting analysis of the unit are obtained for known physical properties of the components of the mixture and their volume ...
