摘要：

To validate the particle motion in flighted rotating drum (FRD), a laboratory FRD was built and operated at 15% filling degree and 10 rpm rotation speed using plastic balls as bed material. The particle tracking velocimetry (PTV) and magnetic particle fracking (MPT) techniques were applied to investigate the particle flow behavior. The 3D particle flow was modeled by Discrete Element Method (DEM) with LIGGGHTS. The height of the barycenter for overall particles and particle instantaneous velocity were calculated from PTV and DEM data. The 3D time-averaged particle velocity distribution obtained from MPT experiment and DEM simulation was compared.
