Abstract:
1. A device for controlling fluid flow comprising: a fluid inlet; a fluid outlet; and a plurality of laterally continuous fluid passageways extending between the fluid inlet and the fluid outlet, each laterally continuous fluid passageway having a cross-sectional area characterized by at least two abutting, offset shapes, the cross-sectional area being completely bounded by a plurality of sides defined by the walls of the laterally continuous fluid passageway, two sides of the plurality of sides meeting at a first point defining the vertex of a first angle between the sides meeting at the first point, two of the sides of the plurality of sides meeting at a second point defining the vertex of a second angle between the sides meeting at the second point, the first angle being equal to the second angle, the first angle and the second angle each exceeding 180 degrees.
