Abstract:
A pressure-exchange ejector (1) comprising:a housing (11) with a primary fluid inlet conduit (2), a secondary fluid inlet conduit (3), and a mixed-fluid outlet conduit(4); and,a supersonic nozzle (5) fixedly mounted within said housing (11), receiving fluid from said primary fluid inlet conduit (2), which accelerates said primary fluid to form a supersonic stream at the nozzle discharge; and,said secondary fluid inlet conduit (3) in communication with a plenum (24) which is internal to said housing (11) and surrounds the downstream end of said supersonic nozzle (5); and,an aerodynamic shroud (10) which receives said secondary fluid from said plenum (24) and directs said secondary fluid towards said primary fluid so as to affect pressure-exchange between said primary and secondary fluids; and,a spindle (14) rigidly mounted to said housing (11); and,a rotor (7) pivotally connected to said spindle (14), said rotor comprising an axi-symmetric revolute body and a plurality of canted vanes (18) fixed to said rotor (7).
