Particle Flow Cell Formation at Minimum Fluidization Flow Rates in a Rectangular Gas-Fluidized Bed.
Abstract
Investigated was the formation of particle flow cells at minimum fluidization gas flow rates in a rectangular gas-fluidized bed. The primary objective is to determine if multiple cell formation occurs as the bed width to height ratio increases. The settled bed height is maintained at a constant level for all runs. The secondary objective is to determine if the presence of external plate heaters at the end walls of the particle bed will alter the particle flow cell formation patterns when energized and to what extent they affect the fluid mixing (heat transfer) flow patterns within the particle flow. Pressure measurements across the bed are used to determine minimum fluidization points and thermocouple probe measurements determined the thermal gradients within the bed for each bed configuration. Visual observations on the external bed movement are included in the determination of the results of this experimental study. (Author)
