英文摘要The magnetic stabilization flow regime could also be created for Geldart-B nonmagnetizable particles provided some magnetizable particles are introduced and the magnetic field is applied. This study aimed to explore the size (dpM) and density (ppM) effects of magnetizable particles on its operating range. The upper limit (UmbH) could not be determined from the APb-Ug down arrow curve but could from analyzing the variation of APb-fluctuation with increasing Ug. Due to the variation of UmfH (lower limit) with dpM and ppM, both UmbH-UmfH and (UmbH-UmfH)/UmfH were used to quantify the operating range of magnetic stabilization. UmbH-UmfH varied hardly with dpM but increased significantly with decreasing ppM. (UmbH-UmfH)/UmfH increased as dpM or ppM decreased. It was more difficult for the nonmagnetizable particles to escape from the network formed by the smaller/lighter magnetizable particles. For the same magnitude of change, dpM had a stronger effect than ppM on (UmbH-UmfH)/UmfH. Neither UmbH-UmfH nor (UmbH-UmfH)/UmfH varied monotonously with the minimum fluidization velocity of the magnetizable particles, indicating that no straightforward criterion for matching the magnetizable particles to the given nonmagnetizable particles could be established based on their minimum fluidization velocities to maximize the operating range of magnetic stabilization.
