Shan-Chen model is a numerical scheme to simulate multiphase fluid flowsusing Lattice Boltzmann approach. The original Shan-Chen model suffers frominability to accurately predict behavior of air bubbles interacting in anon-aqueous fluid. In the present study, we extended the Shan-Chen model totake the effect of the attraction-repulsion barriers among bubbles in toaccount. The proposed model corrects the interaction and coalescence criterionof the original Shan-Chen scheme in order to have a more accurate simulation ofbubbles morphology in a metal foam. The model is based on forming a thin film(narrow channel) between merging bubbles during growth. Rupturing of the filmoccurs when an oscillation in velocity and pressure arises inside the channelfollowed by merging of the bubbles. Comparing numerical results obtained fromproposed model with mettallorgraphy images for aluminum A356 demonstrated agood consistency in mean bubble size and bubbles distribution
