Two-dimensional discrete particle model: Comment on the numerical simulation of cluster flow behavior in the riser of circulating fluidized beds by Liu and Lu

摘要

In a recent paper, Liu and Lu [ 1 ] reported the results of a numerical study on the cluster flow behavior in the riser of circulating fluidized beds using a two-dimensional discrete particle model (2D-DPM). Below we discuss the severe shortcomings of the phase coupling scheme used in the context of a two-dimensional DPM.
