Abstract

Analytical solutions were obtained for the virtual mass coefficient (CV) of a growing and collapsing bubble controlled by the following causes: thermal diffusion and mass diffusion. Expressions were derived for CV of bubble growth and collapse controlled by thermal diffusion, at high and low Jakob numbers. The solutions were validated by their asymptotic approach to the limit of the constant volume bubble as well as to the limit of the single growing bubble in a system of two growing bubbles. Some avenues for future research were pointed out. © 2006 American Institute of Chemical Engineers AIChE J, 2006
