| Outline of Final Research Achievements |
Experimental work has been done to obtain basic knowledges of a newly proposed process for chemical reaction enhancement and mass transfer enhancement using a Helmholtz resonance vessel under the imposition of ultrasound. The advantage of this process is excitation of the resonance using a compact size vessel.
Estimation of local chemical reaction rate and its time dependence in the reaction vessel has been achieved under the suppression of convection. Furthermore, the chemical reaction rate might be enhanced using the Helmholtz resonance vessel.
