Abstract: A rotor is disclosed comprising a drive disk and a plurality of driven disks in a stack, the stacked disks in spaced relationship along the rotational axis thereby forming inter-disk spaces. A centrally positioned aperture is provided in each of the driven disks, opening into the inter-disk spaces. A hub is connected to the drive disk for communication with a drive shaft, and there is a plurality of axial vanes within the apertures and attached to the disks, wherein rotation of the rotor causes fluids to be drawn into the apertures and then into the inter-disk spaces. The rotor can be employed with centrifugal pumps and mixers.

Abstract: A geothermal turbine for converting the energy of two-phase geothermal fluids to rotary power includes a housing having a generally cylindrical rotor chamber with a circular manifold, and a plurality of peripheral nozzles for communicating fluid to the rotor chamber, and a rotor mounted coaxially within the chamber incuding a plurality of converging overlapping blades mounted around a central hub and positioned within the rotor for engagement by fluid from the nozzles.
