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) |
