ABSTRACT:
A fluid flow control system for use with turbines, such as the Tesla-type turbine, where the power fluid contains large amounts of impurities and where it is desired to closely modulate the flow of the fluid to the turbine. The fluid flow channels to the turbine wheel are defined by a plurality of cooperating fluid flow confining blades which may be adjusted to controllably vary the cross-sectional area of the fluid flow channels. The convergent inlet portions and substantially parallel outlet portions of the fluid flow channels as defined by the blades provide a geometry which is highly conducive to the dampening of upstream turbulence and to the injection toward the turbine wheel of an essentially laminar jet. The configuration of the blades and the manner of their adjustment is such that the angular convergence of the inlet portions and the parallelism of the outlet portions of the channels does not change as the blades are adjusted to vary the cross-sectional area of the channels.
