Abstract
An apparatus comprising a longitudinally extending housing having a fluid inlet port and a fluid outlet port; a plurality of spaced apart members rotatably mounted in the housing to transmit motive force between fluid introduced through the fluid inlet port and the spaced apart members, the spaced apart members having an upstream end and a downstream end; and, at least one fan member positioned in series with the spaced apart members.
Claims16
A Prandtl layer turbine comprising:
- (a) a longitudinally extending housing having a fluid inlet port and a fluid outlet port;
- (b) a plurality of spaced apart members, each spaced apart member having a surface for passage of fluid from an inner opening in the spaced apart member to an outer edge of the spaced apart member, the spaced apart members being rotatably mounted in the housing to transmit motive force between fluid introduced through the fluid inlet port and the spaced apart members due to a boundary layer which is formed adjacent the opposed surfaces of the spaced apart members as they rotate, the spaced apart members having an upstream end and a downstream end;
- and,
- (c) at least one fan member having at least one blade and positioned between two of the spaced apart members for directing fluid into the inner opening of the spaced apart members.

A Prandtl layer turbine comprising:
- (a) a housing having a fluid inlet port and a fluid outlet port;
- (b) a shaft rotatably mounted in the housing;
- (c) a plurality of spaced apart members mounted on the shaft and rotatable therewith, each spaced apart member having a radial inner end defining an inner opening, a radial outer end and a pair of opposed surfaces extending therebetween defining a continuous fluid flow passage between the inner opening and the radial outer end, each surface having a radial inner portion and a radial outer portion, the spaced apart members being rotatably mounted in the housing to transmit motive force between fluid introduced through the fluid inlet port and the spaced apart members due to a boundary layer which is formed adjacent the opposed surfaces of the spaced apart members as they rotate, the spaced apart members having an upstream end and a downstream end;
- and,
- (d) at least one fan member having at least one blade and positioned between two of the spaced apart members for assisting in withdrawing fluid from the Prandtl layer turbine.

An apparatus comprising:
- (a) a first Prandtl layer turbine comprising a plurality of spaced apart member having a radial inner end defining an inner opening, a radial outer end, an outer diameter and a pair of opposed surfaces extending therebetween defining a continuous fluid flow passage between the inner opening and the radial outer end, each surface having a radial inner portion and a radial outer portion;
- and,
- (b) a second Prandtl layer turbine comprising a plurality of spaced apart member having a radial inner end defining an inner opening, a radial outer end, an outer diameter and a pair of opposed surfaces extending therebetween defining a continuous fluid flow passage between the inner opening and the radial outer end, each surface having a radial inner portion and a radial outer portion wherein at least some of the spaced apart members of the first Prandtl layer turbine have an outer diameter that is different than the outer diameter of at least some of the spaced apart members of the second Prandtl layer turbine.
