The growth rate of a vapor bubble between two-phase bubbly flow in a viscous superheated binary mixture under the effect of heating source and sink is introduced. The problem is solved analytically using the modification of Mohammadein et al. on the method of Plesset and Zwick. The pressure difference is described in terms of mass diffusion fraction in superheated binary mixture. The previous models of Scriven, Plesset-Zwick and Mohammadein et al. are obtained as special cases of the presented model. The growth of the vapor bubble is affected by mass diffusivity, the vaporized mass diffusion fraction, initial mass fraction and initial viscosity. The present model performs a good agreement with experiment.
