Abstract

Abstract

Phenomenal and theoretical analysis on the evolution of bubble contact diameter during bubble growing is presented in this paper,and it was found that the bubble contact diameter is dependent on the bubble growth rate and bubble radius strongly.By analyzing the regarding experimental data published in the literature,the relation between dimensionless bubble contact diameter,and dimensionless bubble growth time is obtained;based on this relation,a correlation relative to dimensionless bubble growth rate and dimensionless bubble radius are proposed for prediction of bubble contact diameter.With proper values of coefficients,a_w and n_w,this correlation can well predict the bubble contact diameter data published in the literature,with an error within ±20%.
