Investigation of Cavitation Phenomena in Valve Port of a High Frequency Electro-hydraulic Digital Rotary Valve

With the FLUENT software,by studying the flow field in the chambers of 2D digital valve,this paper explored the cavitation variation rule in extreme situations with an attempt to find the effects on valve port flow by bubble precipitating,developing and collapsing during the periodical and high-speed on-offs.The results show that cavitation causes flow rate congestion,and that the pressure fluctuation caused by the bubble collapse brings significant nonlinear impact on the valve controlled cylinder,which reduces accuracy of the valve ports' output waveform and output stability of the valve controlled cylinder vibrator.
