Effect of Apparent Solid’s Viscosity on the Hydrodynamics of Fluidized Beds

The dynamics of bubbles, the flow of gas and solids through the emulsion phase, and interchange of flowing gas between these two phases play a dominant role in heat transfer, mass transfer and solid-catalyzed chemical reactions. The pattern of gas flow through the bubbles has an effect on the degree of gas-solids contacting and under certain conditions a high degree of by-passing can occur. This research is aimed at understanding the aspects of bed hydrodynamics, especially to investigate the gas flow patterns inside the bubbles and solids’ mixing in a fluidized bed.
