Magnetic Stabilization of Fluidized Beds of Magnetizable Particles
In the previous chapter, a number of works were reviewed that showed that gas-fluidized beds can only be stabilized in a nonbubbling regime when interparticle attractive forces become comparable to particle weight. In the absence of sufficiently strong natural attractive forces, interparticle forces may be induced by an external field, which may lead to stabilization. This is the case considered in this chapter, in which the externally imposed magnetic field induce attractive contact forces between the particles.
