Abstract: A vortex generator including an annular bearing for mounting on an interior surface of an exhaust line. The vortex generator further includes an annular blade assembly mounted on the annular bearing. The annular blade assembly includes a leading face with an upstream opening having a first radius. The annular blade assembly further includes a trailing face with a downstream opening having a second radius, wherein the upstream opening and the downstream opening are centered around a longitudinal axis of the exhaust line, and the second radius is different from the first radius. The annular blade assembly further includes a side extending from the leading face to the trailing face, wherein the side has a plurality of openings, each opening of the plurality of openings containing a blade, and each opening of the plurality of openings extends beyond the annular bearing in a direction parallel to the longitudinal axis.

Abstract: A vortex generator for an exhaust system includes an annular bearing for mounting on an interior surface of an exhaust line. The vortex generator further includes a flow splitter mounted on the annular bearing. The flow splitter includes a leading face with an upstream opening. The flow splitter further includes a trailing face with a downstream opening, wherein the upstream opening and the downstream opening are centered around a longitudinal axis of the exhaust line. The flow splitter further includes a side extending from the leading face to the trailing face, wherein the side has a plurality of openings, each opening of the plurality of openings containing a blade, and wherein a trailing side of each blade faces the longitudinal axis.
