The present invention features a fluid flow regulator that functions to influence fluid flow across an airfoil or hydrofoil, as well as various rotating or rotary devices, including propellers, impellers, turbines, rotors, fans, and other similar devices, as well as to affect the performance of airfoils and hydrofoils and these rotary devices subjected to a fluid. The fluid flow regulator comprises a pressure recovery drop that induces a sudden drop in pressure at an optimal pressure recovery point 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 fluid flow regulator functions to regulate the pressure gradients that exist along the surface of an airfoil or hydrofoil. 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 regulates pressure gradients. Reducing the pressure drag in turn increases pressure recovery or pressure recovery potential, which pressure recovery subsequently reduces the friction drag along the surface. Reducing friction drag decreases the potential for fluid separation, and reduces the separation and separation potential of the fluid.
