TL;DR: In this article, a new drag model for TFM simulation in gas-solid bubbling fluidized beds was proposed, and a set of equations was derived to determine the meso-scale structural parameters to calculate the drag characteristics of Geldart-B particles under low gas velocities.

TL;DR: In this paper, magnetic Fe 3 O 4 particles were prepared from copper/iron ore cider by precipitation oxidization method and the yield of Fe was 82.6 at% XRD, TEM, SEM, EDS and microwave network analyzer were used to characterize the particles.

TL;DR: In this paper, the simulation of bubbling fluidized beds (BFB) residence time distribution (RTD) based on the structure-based drag model is conducted for the single and binary gas-solid phases systems, a comparison of computed results with experimental data proves that their model is applicable to both systems with better accuracy.

TL;DR: Lu et al. as discussed by the authors extended the EMMS-DPM method to simulate the residence time distribution of polydisperse particles in a continuously operated multiple-chamber fluidized bed with a calculation of physical time of up to one hour.

TL;DR: In this article, the authors provide a deeply analysis of the flow behavior of bubbling fluidized beds with fine particles in two-and three-dimensional (3D) conditions, and computational fluid dynamics (CFD) simulations of agglomerates fluidization are carried out coupled with the modified agglerate-force balance model.
