An apparatus comprises 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 members; each member having a pair of smooth opposed surfaces, each surface having an inner portion and an outer portion; and, at least one of the members having a width that is increased at at least one discrete location to alter the fluid flow over the surface of that member.

[ We claim:] [1.]1. An apparatus comprising:(a) a longitudinally extending housing having a fluid inlet port and a fluid outlet port;(b) 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 members, a pair of adjacent spaced apart members defining a fluid flow space therebetween having an inlet end and an outlet end;(c) each member having a pair of smooth opposed surfaces, each surface having an inner portion and an outer portion, the fluid passing over the surface forming a boundary layer; and,(d) at least one of the members having a width that is increased at at least one location with respect to the surrounding surface of the member, the location having the increased width is positioned to enhance delamination of the boundary layer.
