Abstract
A mixing device for mixing two or more flowing fluids in a flow duct in which the fluids to be mixed flow along a dividing wall (22), includes a plurality of vortex generators mounted on a downstream end of the dividing wall. The vortex generators (9) have surfaces which project into the duct, and around which flow occurs freely. Each vortex generator includes two side surfaces connected at a lead connecting edge which stands perpendicularly to the dividing wall (22) and is the edge acted upon first by the flow. A top surface consists of two sectional top surfaces (1, 2) which are connected to one another via a top connecting edge (10). Downstream rear edges (5, 6) of the sectional top surfaces (1, 2) are oriented at an angle (.gamma.) with the dividing wall (22), as a result of which, the the rear edges (5, 6) lie on an opposite side of the dividing wall (22)), with respect to the side surfaces (11, 13). A base surface consists of two sectional base surfaces which are connected to one another by a base connecting edge and to the sectional top surfaces by the rear edges (5, 6).
