  • a fluid inlet;

    a fluid outlet; and

    a plurality of fluid passageways extending between the fluid inlet and the fluid outlet, each 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 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.
