Abstract

A bladeless conical radial rotary machine method and system are disclosed. Turbo-machinery and methods are disclosed for a bladeless conical radial rotary machine wherein fluid is directed axially within the pump body to produce an axial output. The rotor comprises a plurality of spaced apart conical elements. The fluid is smoothly directed to any number of subsequent boundary layer pumping stages which are axially positioned with respect to each other. The fluid is smoothly directed to any number of subsequent boundary layer pumping stages which are axially positioned with respect to each other. A coupling between pumping stages is disclosed.

Claims

1. An apparatus comprising:

a first rotary machine operable for transformation of energy between rotary mechanical energy and fluid kinetic energy, the rotary machine comprising;

a drive shaft;

a tubular housing defining a fluid input and a fluid output and a rotor operating region;

a rotor mounted within the rotor operating region for rotation about a rotor axis of rotation through the drive shaft, the rotor comprising a first rotor end and a second rotor end, the axis of rotation extending between the first rotor end and the second rotor end, the rotor operating region being positioned between the fluid input and the fluid output; and

a plurality of rotor elements for the rotor, the plurality of rotor elements being axially spaced from each other along the rotor, the plurality of rotor elements comprising a plurality of surfaces oriented on the rotor so as to be concentric to the rotor axis of rotation, the plurality of rotor elements axially spaced a distance RD between the rotor elements, defining therebetween a plurality of radial flow paths each having a path width PW defined by the distance RD between the rotor elements, the plurality of rotor elements defining a plurality of centrally positioned apertures that collectively define an unrestricted interior opening that surrounds the drive shaft and connects to the plurality of radial flow paths to permit radially outwardly fluid flow through the plurality of radial flow paths, the unrestricted interior opening receiving fluid flow from the fluid input to provide the radially outwardly fluid flow through the plurality of radial flow paths;

a solids port through which the solids are removed from the fluid;

a motor attached to the drive shaft;

a processor in data communication with a computer readable medium and the motor; and

a computer program stored in the computer readable medium, the computer program comprising instructions executed by the processor, the computer program further comprising instructions to adjust a speed value for the motor wherein the speed value is adjusted inversely proportional to a density FD of the fluid.

2. The apparatus of claim 1, wherein the motor is an electric motor and density FD of the fluid is estimated by current flowing to the electric motor.
