Abstract
An active and passive boundary layer control system and method for reducing boundary layer separation and the resulting form drag from ground vehicles. Tubings with multiple venturis connected in series are attached to the side and/or roof of the ground vehicle. A flow of compressed air is created by an engine auxiliary, e.g., a turbocharger or a supercharger, or by a designated blower and injected into the tubings. Suction created by the venturis actively removes decelerated fluid from the boundary layer and keeps the boundary layer flow attached. Optionally, the system exhausts the air in concentrated free jets along the vehicle body to a series of passive boundary layer control devices, such as vortex generators.
