METHOD OF LIQUID FLOW OSCILLATIONS PRODUCTION AND HYDRODYNAMIC OSCILLATIONS GENERATOR Russian patent published in 2017 - IPC F15B21/12 B06B1/20 

FIELD: machine engineering.

SUBSTANCE: group of inventions refers to the hydrodynamic systems and can be used in the fields of industry, that use the fluid flow pulsating condition. In the method of liquid flow oscillations production, the liquid from the pressure main 3 is directed to the vortex chamber 1 by means of the cyclonic ports 2. The liquid is then swirl to form the vortex and it is divided into the low pressure central part, that is discharged through the nozzle 8 and the peripheral part with the high centrifugal pressure, that is discharged through the side gap into the main pipe 4 with the elastic element 5. At the same time, the liquid from the pressure main 7 is directed through the additional channel 6 to the main pipe 4. In this case, the time of pressure increase in the main pipe 4 upto the centrifugal pressure value in the side gap is determined by the elasticity value of the element 5. As a result of the elastic interaction, the stable state of the vortex energy interaction with the element 5 is broken, which leads to the self-oscillations excitation of the liquid between them. In this case, the vortex rotation speed and the liquid discharge from the nozzle 8 are automatically oscillated.

EFFECT: increase of the discharge fluctuations intensity.
