Based on CPFD numerical simulation,the impact of the parameters such as spouting velocity,background flow rate and particle size on the gas-solid two-phase flow field in a fluidized bed was studied.The research shows that the spouting velocity has the greatest influence on the flow field characteristics of the fluidized bed.Within a certain range,the faster spouting velocity and the slower background flow rate will be favorable to the internal circulation of the fluidized bed.The effect of particle size on the gas-solid flow field in fluidized bed does not show regular pattern.
