Is intermittent cavitation ok? Is a little bit of cavitation OK in a hydraulic system?
I am sizing an orifice valve and found that the flow will begin to choke (like a gas) at a cavitation number ([Pu-Pv]/[Pu-Pd]) of about 1.5 or more. After a bit of research I think I can conclude that cavitation is going on.
The valve will be used in a landing gear actuator so it will not see constant flow. Is intermittent cavitation safe? Is there any published information about how long it will take for any damage to occur?
