VORTEX EJECTOR Russian patent published in 2019 - IPC F04F5/42 

FIELD: power engineering.

SUBSTANCE: invention relates to wind power engineering. Ejector comprises a housing, tangential gas flow inlet nozzles, a mixed flow outlet tangential branch pipe, an injected flow inlet pipe arranged coaxially to the housing of the apparatus. Vortex ejector housing is formed of coaxially interconnected air intake systems for input of active flow of solid medium, elements of generation of this swirled flow, consisting of n+1 hollow elements, in the form of coaxially located cavitary truncated hyperboloids of rotation with arrangement in their cavity of vertical separation blades-partitions of spiral shape, forming spiral channels and forming around the axis of rotation of the active flow a vortex chamber in the form of a cylindrical low pressure zone, causing ejection of passive flow, and the base of the vortex ejector is made in the form of a truncated hyperboloid with an ejection hole, through which the passive flow enters a cylindrical low pressure zone, where it is mixed with the active flow and forms a mixed vortex quasi-potential laminarized flow inside the vortex chamber.

EFFECT: reduction of energy losses during use of wind energy.
