A boundary layer turbine comprising a housing having an inlet and an outlet, the inlet receives a flow of pressurized fluid; a shaft extending longitudinally through the housing and journaled for rotation about its longitudinal axis relative to the housing; a plurality of nested cylindrical tubes of progressively wider diameter arranged coaxially about the shaft and connected to the shaft, wherein adjacent tubes define a cylindrical fluid passageway there-between that is in fluid communication with the inlet and the outlet, thereby the plurality of tubes define a plurality of passageways; at least one nozzle coupled to the inlet configured to direct the flow of fluid from the inlet into the plurality of passageways and against the plurality of tubes at an angle to a normal plane to the curvature of the plurality of tubes and at an angle to the longitudinal axis of the shaft, wherein the angled flow of fluid imparts rotation to the plurality of tubes and the shaft and flows towards the outlet where the fluid is discharged, and wherein the rotating shaft may be used to provide kinetic energy. |
