| Summary: | 碩士 === 國立中山大學 === 機械與機電工程學系研究所 === 107 === This study numerically simulates the shape development interaction and dynamic full flow between the two bubbles on the solidification form. COMSOL software is used to calculate conservation equations of mass, momentum, energy and concentration in the entire domain by incorporating with temperature to distinguish solid and liquid phases, and phase-field function to distinguish liquid and gas phases. The results show that the bubble shape is strongly affected by convection and the solidification rate.
