<P>PROBLEM TO BE SOLVED: To provide a jet mixing device and a combustion device, in which fluids are mixed with high efficiency by rapidly forming a hollow longitudinal vortex, and a mixed state can be easily controlled. <P>SOLUTION: A jet mixing device 1 includes doubly arranged nozzles and mixes a first fluid F jetting from an inner pipe nozzle 2 and a second fluid A jetting from an outer pipe nozzle 3. The device includes: rotating means 5 for rotating the outer pipe nozzle 3 around a center axis O parallel to the flow direction of the second fluid A; and a honeycomb section 4 disposed inside the outer pipe nozzle 3 and having a plurality of holes where the second fluid A can circulate. By rotating the honeycomb section 4 associated with rotation of the outer pipe nozzle 3 by the rotating means 5 to impart rigid rotation to the second fluid A circulating in the honeycomb section 4, the jet mixing device 1 generates a hollow longitudinal vortex having an extreme value of vorticity in a prescribed annular region apart from the center axis O. <P>COPYRIGHT: (C)2012,JPO&INPIT |
