<P>PROBLEM TO BE SOLVED: To provide an apparatus and a method for agitating fluid by which complex apparatus structure is unnecessary, gas-liquid mixed fluid can be agitated while preventing fall of pressure loss and fall of critical flow rate and effective production of homogeneous minute bubble fluid can be attained. <P>SOLUTION: An agitating part is divided into a prestirring region A and a stirring region B and a porous body 11 with a relatively large numerical aperture is disposed in the prestirring region A and a porous body 12 with a relatively small numerical aperture is disposed in the stirring region B. The gas-liquid mixed fluid L flowed-in from a flow part 21 is agitated while successively passing the porous body 11 in the prestirring region A and the porous body 12 in the stirring region B. <P>COPYRIGHT: (C)2013,JPO&INPIT |
