英文摘要	This work aimed to solve the controversies about defining and determining the minimum fluidization velocity (U-mf) in the magnetized fluidized bed (MFB). It should be defined rigorously from the physics behind the secondary phenomena such as bed pressure drop and particle motion. Since U-mf demarcates the transition from the fixed-bed to the fluidization flow regime, it could not be determined from the Delta P-b-U-g down arrow curve but could from the Delta P-b-U-g up arrow curve. Moreover, the initial fixed bed for measuring this curve must meet its definition. For the MFB with purely magnetizable particles, it could be obtained via decreasing U-g gradually from full fluidization to zero at H = 0 kA/m to minimize the wedging effect. For the MFB with magnetizable and nonmagnetizable particles, such a decrease of U-g should be quick to simultaneously minimize the wedging effect and segregation. The as-determined U-mf remained invariant with H in both types of MFBs. (C) 2021 Elsevier B.V. All rights reserved.
