FIGURE 12.4
H g versus the square of the water superficial velocity at a current intensity of:
(a)2A;(b)5A;(c)9A. A is the fixed bed zone, B is the fluidized bed zone,
and C is also a fluidized zone but where the velocity is very high and the top
of the bed o particles is well above the coil, and thus, the magnetic traction
force is very low. (From Estevez et al. 1995.) ( Continued )
