Vortex generator

Abstract

The present invention provides a vortex generator that in one embodiment includes an apex having a first width; a rear face having a second width being greater than the first width; a first and second sidewall each extending from the first width of the apex to the second width of the rear face, wherein at least a portion of each of the first and second sidewall have a peak including a convex surface; and a concave work surface positioned between the peak of the first and the second sidewall, wherein the concave work surface has an intake at the apex and an outlet at the rear face. In another embodiment, the exterior faces of the sidewalls include a planar surface.

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application 60 / 764,080, filed January 31, 2006, the entire contents and disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The invention relates to a structure which, in one embodiment, reduces aerodynamic drag in a transport system. Background technique [0004] Aerodynamic drag is usually caused by some form of separation, such as airflow separation, etc. Airflow separation typically occurs on the lateral surfaces of the motor vehicle and behind the trailing edge surface of the moving vehicle 10 and typically results in the formation of a vortex 1 whose flow axis is perpendicular to the direction of motion M1 of the motor vehicle, as depicted in FIG. 1 . Air flow separation is generally related to the adverse pressure gradient that develops behind the rear face 2 of the moving vehicle 10 . In addition, as the ai...

Problems solved by technology

In addition, as the airflow pressure 3 on the front face 4 of the vehicle 10 becomes larger, the resistance to the forward motion M1 of the vehicle 10 also becomes larger.
