1. A static mixer for mixing a fluid flow having at least two components, the static mixer comprising:
a mixing conduit defining an inner surface that comprises a first inner surface, a second inner surface that extends from the first inner surface, and a third inner surface that extends from the first inner surface to the second inner surface, such that the first, second, and third inner surfaces define a mixing passage configured to receive the fluid flow, and the first and second inner surfaces are offset by a first acute angle, the first and third inner surfaces are offset by a second acute angle, and the second and third inner surfaces are offset by a third acute angle; and
a mixing element positioned in the mixing passage and defining a substantially triangular cross-section, wherein the mixing element is configured to contact the first, second, and third inner surfaces and defines a first mixing baffle that extends from a leading edge to a trailing edge, the first mixing baffle configured to divide the fluid flow into a first portion and a second portion and the leading edge defined by a plurality of leading edge portions obliquely angled relative to each of the first, second, and third inner surfaces of the mixing conduit.
