Mixer ejector flow distributor.

摘要

An apparatus is disclosed for attaining improved flow uniformity through and at the exit of an air duct (11) by mixing and distributing the air flow. The apparatus has a wall (21) containing a plurality of convoluted corrugations or lobes arranged in conjunction with an airfoil shaped faired body (22) to form an ejector passage between the wall (21) and the faired body (22). There is a primary flow passage (71) on the side of the wall (21) opposite the ejector passage. The corrugations extend into both the primary flow and ejector flow passages so that a lobe in one passage is a trough in the other passage. Air flow in the primary flow passage (71) acts to cause a flow through the ejector passage and thus a suction in the inlet to the ejector passage. The suction acts upon streamlines around the apparatus to obtain improved downstream air flow performance. One described embodiment of the flow distributor increases the spreading half angle ( beta ) at the exit of an air flow duct. <IMAGE>
