摘要：
The dynamic behavior of magnetic medium has a significant effect on the density of air-dense medium fluidized bed (ADMFB), and the density is an important parameter of ADMFB. This article introduces the model of ADMFB using multifluid hydrodynamic theories. The flow pattern of dense medium and the vertical density distribution in the ADMFB is obtained at the gas speed of 0.157 m/s. All the computed results are in a good agreement with experimental data. The results show that the flow pattern of dense medium ascends near the center and descends near the wall, and the density is stable along the vertical in the ADMFB.
