was utilized to simulate the lateral diffusion behavior of large solid particles in a 900 mm×100 mm×1200 mm quasi-three dimensional fluidized-bed.Before the simulating
verification had been performed in accordance with previous experimental studies to ensure the reliability of CPFD.The effects of the tracer particle diameter and the fluidizing air velocity on lateral dispersion coefficient of large solid particles in dense zone were investigated by the method of tracer particle.The results showed that the bubble behavior was the major factor of solid mixing in dense zone
which had been confirmed in many literatures.An increased gas velocity or a reduced tracer particle diameter resulted in an increased lateral dispersion coefficient.
