IPC: G01F1/32
Filed: 1989-06-14
Abstract: PURPOSE:To enable generation of vibration of a fluid by a simple construction by jetting the fluid from three-dimensional nozzles into a sharply expanded channel in a case body. CONSTITUTION:A jet stream of a prescribed flow rate is jetted into a case body 1 from three-dimensional nozzles 4 and 4' having openings 3 and 3' which are made in the upstream-side end wall of the case body 1 having a rectangular section and a prescribed length and which have a prescribed section having a height and a width or a diameter in a prescribed range of ratios to the height and the width of the case body 1. Thereby the jet stream accompanied by two conspicuous vortex regions generated, strengthened and attenuated in the opposite ends of the jet stream is made to stick onto one lateral wall, first, by a Coanda effect. Next, the fluid energy of a vortex flow on the non-sticking side is made to pass through gaps between the three-dimensional nozzles 4 and 4' and the upper and lower wall surfaces of the case body 1 and to run onto the sticking vortex side of low pressure. Thereby the inclination of the jet stream toward one lateral wall is lessened and sticking of the stream is changed over onto the other lateral wall. By changing over this inclination of the jet stream alternately and regularly, vibration of a fluid can be generated.
