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.
