Abstract:

A method and apparatus are provided for suppressing flow-induced cavitation in a fluid flow. At least one acoustic transducer is coupled to the fluid flow in region that is susceptible to the formation of cavitation bubbles. The transducer or transducers applies an acoustic add to the fluid flow in order to raise the cavitation threshold pressure of the fluid flow above the total local pressure including the press ore drop induced by the fluid flow and the pressure due to the acoustic field.
