Abstract�� The simulation was carried out using standard k-�� model to study the rotational gas flow field in spout-fluidized bed based on Fluent software.A flow structure which contributes to the operation of granulation and coating was achieved.Experimental measurement showed that the simulation results were reliable.The research provided valuable reference for the design and structure optimization of spout-fluidized bed.
