Marangoni convection becomes dominant under microgravity and micro-scale environments. In the micro-scale environment, the theory of macro-scale transport phenomena including fluid flow, heat and mass transfer can not be maintained. In addition, Marangoni convection with concentration gradient of surfactant is very difficult problem to analyze. To analyze mass transfer of some surfactants, we have to consider adhesion of surfactant to the interface, interaction between surfactants and macro-scale mass transfer. In this study, a numerical model for calculating the micro-scale phenomena has been developed. Multiphase simulation model including heat and mass transfer was developed and coupled with Discrete Element Method to analyze micro-scale mass transfer.
