The third part of the series concerning the magnetic field assisted fluidization focuses the attention on the heat transfer phenomena. The discussion covers the gas-fluidized beds only. In contrast to the hydrodynamic problems the heat transfer problems (temperature distribution in both the axial and radial directions as well as gas-to-particles and bed-to immersed surface heat transfer) have paid little more attention. The paper made an attempt to re-examine the data concerning the heat transfer phenomena in gas-fluidized beds of ferromagnetic particles controlled by external magnetic field. Data from various sources have been collected and re-evaluated critically from a unified point of view.
