摘      要：Particle distribution in the cross-section of the flighted rotating drum(FRD)is critical to the analysis of heat and mass transfer between gas and *** this work,the particle tracking velocimetry(PTV)method is applied to study the influence of the number of flights on the particle motion in *** drum,installed with 1,4,8,or 12 rectangular flights,is filled with plastic balls to 15%and operated at various rotating speeds ranging from 10 rpm to 30 *** results show that the number of flights has different effects on the holdup ratio and cascading rate of single flight and active *** 8 and 12 flights,the FRD produces a larger and more stable particle ratio of the dilute ***,DEM simulations agree with PTV measurements,whereas literature models show significant deviations.
