  • Vortical flow rotor
    Patent number: 7488151
    Abstract: A rotor for use with a fluid flow generator or reactor, said rotor being rotatable about a central axis of the rotor and having a at least one vane arranged, in use, to induce a generally axial fluid-flow into the central axial region of the rotor and an outward flow from the central axial region of the rotor to the outer periphery of the rotor, wherein the at least one vane comprises a vortex generator adapted to accelerate the fluid away from the central axis of the rotor in a vortical motion.
