FASTBACK VORTICOR PIN

A structure for disrupting the flow of a fluid, the structure comprising: (a) a first lateral wall (406) and a second lateral wall (408) spaced apart from one another, yet joined, by a floor (410) and a ceiling (412); and, (b) a vorticor pin (400) extending incompletely between the first lateral wall and the second lateral wall in a direction parallel to an X-axis, the vorticor pin concurrently rising above and extending away from the floor to a height, in a direction parallel to a Y-axis, to provide a gap between the vorticor pin and the ceiling, the vorticor pin comprising: (i) a front surface (402) extending incompletely between the first lateral wall (406) and the second lateral wall (408), the front surface extending above the floor and having an arcuate portion that is transverse with respect to a Z-axis, which is perpendicular to the X-axis and the Y-axis, and (ii) a rear surface (414) extending between the first lateral wall (406) and the second lateral wall (408), the rear surface extending between the front surface and the floor, the rear surface having an inclining section that tapers in height, taken parallel to the Y-axis, in a direction parallel to the Z-axis.
