Single Microparticle Measurement Using an Electrodynamic Balance (III)—Transport Phenomena and Heterogeneous Reaction—

Abstract

This review has touched on the applications of Electrodynamic Balance (EDB) in mass transfer and heterogeneous reaction of droplet. The EDB was adapted to establish the unsteady flow around the droplet by oscillating a 1-Dodecanol droplet by AC electric field. The enhancement of mass transfer was examined from the evaporation rate of single oscillating droplet. Desulfurization reactions of a levitated single Na₂CO₃ droplet were followed by the EDB coupled with a Raman spectroscopy. The mechanism of heterogeneous reaction was discussed from the changes in mass and Raman spectra of the levitated particle. These examples have been demonstrated that EDB was a powerful tool for the kinetic studies of aerosol.
