AbstractThe fluidization behavior of Geldart's group C powders has been studied and the experiments demonstrate that channels and bubbles can be eliminated effectively. Theoretical analysis shows that the fluidization quality is improved due to the formation of a chain structure. Two optical fiber probes are used to measure the size of the bubble in the bed and it shows that the bubble size decreases with increasing magnetic field intensity and magnetic powder fraction. The length of the chain, obtained by using a CA5300 board and modular system, has been found to be strongly influenced by the magnetic field intensity. A mathematical model has been derived through theoretical analysis and the calculated results are in agreement with experimental data. A dimensionless number M(h) is developed to forecast the magnetically condensed state.
