Summary:In an apparatus and method for ejecting an additive for significantly reducing the drag of a first fluid moving relative to a wall, a drag-reducing substance is conditioned by causing a second fluid (5), which includes the drag-reducing substance as a dispersed solid, liquid or gas. to flow through a nozzle (13). The second fluid is then passed by a vortex chamber (4) prior to ejection of the second fluid into the first fluid via an aperture that includes a Coanda surface (8) on a portion thereof. Additional techniques are also disclosed which increase the effectiveness and efficiency of ejecting a drag-reducing substance into a fluid that is moving relative to a wall, and which thus enable multiple layer 10 be established without the undesirable disruption of the boundary layer und without the rapid diffusion of the additives across the boundary layer that occur in prior art ejection techniques.
