Turbine

A turbine rotor assembly including a unitary body including at least one inlet for inlet of a fluid into the rotor assembly and a plurality of flow channels extending through the unitary body and terminating in an outlet portion, the at least one inlet in fluid communication with each of the plurality of flow channels, wherein

• the unitary body is substantially circular when viewed in one orientation and bell-shaped having an arcuate waist when viewed in a perpendicular orientation,
• a respective outlet portion of each of the plurality of flow channels is provided on an outer lateral side edge of a lip of the unitary body, substantially tangentially to the outer lateral side edge of the lip in order to create rotational force and tangential thrust as the fluid exits the respective outlet portion,
• each of the plurality of flow channels is arcuate and continuous without obstruction between the at least one inlet and a converging-diverging nozzle in order to translate axial flow of the fluid into the rotor assembly into radial flow to provide rotation of the rotor assembly,
• each of the plurality of flow channels is discrete and completely separate from one another between the at least one inlet and the respective outlet portion,
• each of the plurality of flow channels is at least partially helical extending from a portion of the unitary body adjacent to the at least one inlet to each respective outlet portion of the plurality of flow channels,
• the unitary body is formed from a single piece construction formed from a metallic or an elastomeric material that is sintered or 3D printed.
