The effect of magnetic field on local heat transfer coefficient in fluidized beds with immersed heating surface

Five different magnetic particles have been used to investigate the effect of a transverse magnetic field on the thermal behavior of a gas fluidized b ed, with an immersed heating spherical surface. The effects of gas superfic ial velocity and magnetic field intensity on the behavior of the temperatur e distribution and the local heat transfer coefficient at different radial and axial positions in the bed was investigated. In the present study a cor relation relating Nusselt number to the magnetic field intensity is propose d.
