METHOD AND SYSTEM FOR REGULATING EXTERNAL AND INTERNAL FLUID FLOW

Title:

METHOD AND SYSTEM FOR REGULATING EXTERNAL AND INTERNAL FLUID FLOW

Document Type and Number:

WIPO Patent Application WO2004001267

Kind Code:

A3

Abstract:

The present invention features a fluid flow regulator (210) that functions to influence fluid flow across a surface such as a rotating or rotary device, including propellers, impellers, turbines, rotors, fans, and other similar devices, structures and hulls or fuselages. The fluid flow regulator (210) comprises a pressure recovery drop (226) that induces a sudden drop in pressure at an optimal pressure recovery point (234) on the surface, such that a sub-atmospheric barrier is created that serves as a cushion between the molecules in the fluid and the molecules at the airfoil's or hydrofoil's surface. More specifically, the present invention fluid flow regulator functions to significantly regulate the pressure gradients that exist along the surface of an airfoil or hydrofoil. Regulation of pressure gradients is accomplished by selectively reducing the pressure drag at various locations along the surface, as well as the pressure drag induced forward and aft of the airfoil or hydrofoil, via the pressure recovery drop.
