Diffusion-Controlled Change in Bubbles Impregnated in Viscous Solutions.

Abstract

The applicabilities of Epstein and Plesset's theory and Lemlich's theory to the change in bubble-size distribution under a constant temperature were studied on bubbles impregnated in homogeneous viscous solutions. The numerical calculation based on Epstein and Plesset's theory that took into account the change in the dissolved air concentration in the surrounding solution agreed well with the measured results, while Epstein and Plesset's theory, which assumed the dissolved air concentration in the surrounding solution to be constant, and Lemlich's theory, did not fit the measured results.
