Hydrodynamic characteristics of magnetically stabilized fluidized admixture beds of iron and copper particles

摘要

Hydrodynamic characteristics of fluidized beds of pure iron(1416μm), copper(934μm) and their admixture(25,50 and 75 mass/100)particles when exposed to a uniform magnetic field collinear with the gas flow are investigated. Bed pressure-drop data taken as a function of increasing and decreasing gas velocities(up to about 8 m/s)for different values of magnetic-field intensity over a wide range(0 to 17 272 A/m)are employed to determine the superficial minimum bubbling and fluidiza- tion gas velocities at ambient temperature and pressure.
