THE STRUCTURE OF MAGNETIZED-FLUIDIZED BEDS

Magnetized-fluidized beds exhibit a behaviour - from the point of view of hydrodynamics as well as of heat and mass transfer - which can be explained in terms of a rearrangement of particles: when a magnetic field is applied, particles align themselves, forming 'chains' following field lines. Bed voidage and pressure drop measurements have been used to show this effect and to calculate the degree of particle arrangement in these beds. Data obtained in mass and heat transfer processes have corroborated the previous observations.
