A static mixer 10 for mixing a fluid flow having at least two components is disclosed, as well as a method for mixing first and second components with the static mixer 10. The static mixer 10 includes a mixing conduit 20 having a first inner surface 38a, a second inner surface 38b that extends from the first inner surface 38a, and a third inner surface 38c that extends from the first inner surface 38a to the second inner surface 38b. The first, second, and third inner surfaces 38a, 38b, 38c define a mixing passage receiving the fluid flow. The first and second inner surfaces 38a, 38b are offset by a first acute angle, the first and third surfaces 38a, 38c are offset by a second acute angle, and the second and third surfaces 38b, 38c are offset by a third acute angle. The static mixer 10 includes a mixing element 100 positioned in the mixing passage.
