Fluidization of initially segregated binary mixtures has been investigated for particle systems of the same material. This paper reports experiments conducted in 0.055m diameter fluidizes bed for binary mixtures composed of sands whose sizes ranged from 450 to 1450mm. An empirical relationship, Utf = 0.95 UF (dR)0.87, was derived in terms of the minimum fluidization of the smaller particle, UF ...

Accurate calculation of the minimum fluidization velocity makes it possible to reduce raw material losses due use excessively high or low air velocities. This is particularly true for impingement fluidization, which little studied, especially when treating parachute-shaped material. paper focused on determining drag coefficient cauliflower florets, mushrooms, and broccoli. Analysis critical par...

The aerodynamic behavior of wet forestry biomass particles mechanically shaken in a fluidized bed was analyzed with turning velocity between 0.5 and 2 r.p.s. It was concluded that the agitation exerts an important effect on the fluidization of wet biomass particles. The effect of the agitator is not relevant if the particles have low humidity content. In addition, a methodology based on the Erg...
