Abstract

In this work, an extended CFD-DEM approach is developed to study the gas-solids flow and heat transfer between bed and riser wall in three-dimensional full-loop circulating fluidized bed. The effects of some operational, such as superficial gas velocity and solids inventory, on the heat transfer coefficient between bed and riser wall are investigated. The governing heat transfer modes such as wall-fluid convection, wall-particle conduction, are then discussed to gain better understanding about heat transfer between bed and wall in circulating fluidized beds. This work demonstrates that the developed 3D CFD-DEM approach could be a useful tool to study the coupled fluid flow and heat transfer in such a complex system
