METHOD AND DEVICE FOR VORTEX ENERGY DIVISION OF WORKING FLUID FLOW Russian patent published in 2009 - IPC F25B9/04 

FIELD: power engineering.

SUBSTANCE: in method working fluid flow is swirled with generation of vortex precessing cord, at the same time angle between vectors of axial and full speed is selected in the interval from 0 to 70 degrees. Then flow is accelerated to speed close to maximum, intensely swirled breakage flow is generated in flux with volume oscillations of pressure, and tangential nozzle input of flux into energy division chamber is carried out. In chamber flux is separated into paraxial and peripheral intensely swirled fluxes. Device comprises chamber 1 of energy division, connected with its one end to body 2, and with its other end - to throttle 3, diaphragm 4 with central hole 5. Diaphragm 4 is located in end of body 2 opposite to chamber 1, in which swirler is installed with tangential nozzle inputs, every of which is connected to internal cylindrical surface of body 2 and to inlet nozzle connected to source of working fluid. In channel of each inlet there is a turbulence promoter 12 of flow, installed in normal section of its minimum area. Inlet swirling device is formed with internal channel of inlet nozzle and channel of nozzle inlet. In swirling device at the inlet of nozzle input channel there are blades installed on cylindrical bush.

EFFECT: expansion of method and device application field and efficiency factor increase.
