AbstractBubbling fluidized beds with binary particle mixture have broad industrial applications. The difference in particle size/density leads to segregation phenomenon thus should be taken into account in modeling. In this work, we propose a binary EMMS-bubbling drag model by considering such difference and formation of bubbles which are associated with solid segregation. The model is validated through simulation of two fluidized beds with different binary particle mixtures. The new drag model is found to enable capturing the pronounced movement of bubbles, thus well predicts the segregation behavior, while using conventional drag leads to over-mixing of different particles.
