Solid-gas Fluidization generally pertains to particle-laden flows wherein seed particles of desired size are dispersed in a fluid volume inside a fluidized bed seeder. The present work includes numerical investigation of a simple non-reacting and non-restricted two-phase fluidized bed followed by the experimental analysis of a fabricated non-reacting two-phase fluidized bed seeder. Void fraction of the bed is maintained as 0.53 throughout the analyses owing to absence of chemical reactions. Considering the physical significance of a two phase system (namely particles and beads constituting the bed), agitation of the bed and initial turbulence required for smooth particle entrainment in the flow are of paramount importance, as their ineffectiveness adversely affects the flow physics and measures adopted explain the revamping done in this section. The major drawbacks of agglomerate formation and particle stagnation faced by a two-phase fluidized bed seeder are also relatively minimized. The following paper is presented with a view of articulating the benefits of the fabricated two-phase seeder and also the dependency of experimental analysis on the percentage of bed rise, which is obtained numerically.
