ON A PARADOX OF INFLUENCE OF VOLUMETRIC FLUID DISCHARGE THROUGH THE CAVITY GENERATOR ON OSCILLATION AMPLITUDE RANGE

Юрий Алексеевич Жулай

Abstract


In the paper it was established that increase of volumetric fluid discharge through the generator leads to the increase of volume of separated part of the cavity. Collapse of large volume cavity is not accompanied by the oscillatory component of pressure that is a paradox. This paradox is explained from the physical point of view and from standpoint of existing linear mathematical model of the generator. This is due to the fact that at constant ratio of geometrical parameters of the generator the amplitude range of cavitation self-oscillations is defined by velocity of its wall and not by the cavern size.


Keywords


hydrodynamic cavitation; fluid pressure fluctuation generator; range of pressure fluctuations; velocity of cavern wall
