Patent ID: 8434723

Claim:
An asymmetric tetrahedral vortex generator for placement on a surface, comprising: an elongated tetrahedral shape joined along sharp edges and defined by four triangular sides including a base, a leeward side, a windward side, and a side face, the overall proportions of the shape characterized by the values L 2 , L 1 , h 2 and h 1 , wherein L 1 is an overall length of the side face along the base, L 2 is a length to a widest dimension of the base from a windward most aspect of the shape, h 2 is an overall height of said shape from the base, and h 1 is a width of the base at its widest section, wherein a ratio of L 2 /L 1 is between 0.5 to less than 1.0, h 1 /L 1 is between 0.25 to 0.4, and h 2 /L 1 is between 0.25 and 0.4.
