Abstract
The mixer to mix gas and liquid mutually utilizes the pressure difference in the liquid mixed with gas to produce resonance and sound energy crushing the gas for effective mixing. Through eddy flow, the gas is made to stay in the liquid for longer period so as to result in full mixing. By means of the sound energy resulted from the resonance caused by the interaction between the flowing mixed fluid and the resonator and the sound energy produced by the resonance caused by the mixed fluid sprayed in eddy flow mode owing to the reaction between the reflecting board and the cylindrical rod, the gas may be superfined limitlessly.
