Abstract

PURPOSE: To generate a flow of a large quantity of a fluid at a high speed by accelerating a compressive fluid in a Laval nozzle and the following rectifying section to make a high speed jet, and jetting the high speed jet toward the downstream side by the rectifying section and the arrangement of an opening surface.
CONSTITUTION: When pressurized air is supplied into a pressure accumulating tank 20, the compressed air is introduced into a fluid supply pipe 30 for acceleration. In a Laval nozzle 40, an introduced flow lower than the sound speed is accelerated by a throttle portion 42 and increased in speed to the sound speed region in a throat 41. As the subsequent expanding portion 43 functions as an accelerating nozzle to a flow high than the sound speed, a jet from the Laval nozzle 40 is accelerated to the supersonic region to generate strong negative pressure. In a rectifying section 50, a high speed jet is rectified and a high speed jet which has passed through the rectifying section 50 is blown along the inner wall of a pipeline 12 towards the downstream side to make a high speed stable primary flow. The primary flow is joined to a flow of a driven fluid to make the second flow, which is jetted from the downstream side opening of the pipeline 12.
