This article introduces a type of stochastic model, which we call a multiphase stochastic model, for the particle transport in bubbling fluidized beds, making it possible to take into account the finite velocity of fluidization bubbles and also extra particle transport due to "gulf streaming." An extended analysis of experimental results for particle transport in fluidized beds with gulf stream...

conclusions results indicated that annular fluidized bed reactor’s adsorbers are useful techniques for vocs adsorption. comparison of two particle ranges indicates that in all concentrations and all flow rates of the experiments, smaller particle size adsorption are better. in superficial velocity above the minimum fluidization velocity, pressure drop of fluidized beds are less than the pressur...

We experimentally investigate the effect of vertical vibrations on brittle behavior fine cohesive powders consisting glass beads 5 μm in diameter. This is an attempt to understand a sole role fluidizing Geldart’s group C powders, which known for posing difficulty while fluidization. find that powder column can be compacted, fractured, and effectively fluidized by increasing strengths external v...
