GROWTH OF A GAS BUBBLE IN A SUPERSATURATED LIQUID UNDER THE EFFECT OF VARIANT CASES OF SURFACE TENSION

Abstract

In this paper, the growth of a gas bubble in a supersaturated liquid is discussed for a constant and variable cases of surface tension effect. The mathematical model is solved analytically by using the method of Plesset and Zwick 18 after modified it. The growth process is affected by: diffusion coefficient D, Jacob number J a , surface tension σ, adjustment factor b and void fraction ϕ 0 . The famous formula of Plesset and Zwick is produced as a special case of the results at some values of the adjustment factors. Moreover, for some values of the adjustment factors, good approximation is obtained when a comparison between our results and the result that produced by Hashemi et al., 9 who solved the problem with the method of combining variables.
