Abstract
PURPOSE: To generate a jet stream with a big flow rate by the injection of a pressurized fluid and increase the output efficiency of Coanda engine by providing a Coanda surface continued to the inner wall surface of a training passage while being continued from the inner wall surface of an injection nozzle and bent smoothly. CONSTITUTION: The jet stream of a compressed air injected from an injection nozzle 15 is streamed along a Coanda surface 12 by a Coanda effect and deflected toward a training passage 11 side in response to the shape of the Coanda surface 12 and streamed in the training passage 11. The air in an intake passage 22 is sucked in the training passage 11 so as to be rolled in the jet stream from the injection nozzle 15 partially and surrounded by the jet stream. Therefore, a first stream F1 with a bigger flow rate in comparison with the flow rate of the jet stream from the nozzle 15 is formed in this passage 11. While, this stream F1 is injected in an outside air guide 23 and the open air introduced by an open air introduction part 24 is rolled in the outer periphery side and a second stream F2 whose flow rate is further increased is formed.
