Abstract

A mixing device includes a mixing cavity having a partially open wall and a closed wall. In certain examples, the partially open wall and the closed wall are two separately formed pieces. A downstream side of the mixing device is shaped so as to define a helicoidal groove for circumferentially guiding gas from an outlet opening of the mixing cavity in a downstream direction. An injector sprays reactant into the mixing cavity.
