چکیده
Fluidized bed drying is an unsteady process where particle and gas properties evolve in time. The hydrodynamics its interplay with mass heat transfer changes In this study, experiments a pseudo-2D fluidized setup are performed to obtain insight complex behavior. A coupled image velocimetry infrared thermography technique provides solids velocity temperature fields the bed. Significant hydrodynamic due evaporation of water from porous ?-Al2O3 material for three superficial velocities were observed. 1.25 umf case resulted fixed state, but after 580 s inversion took place. 1.50 1.75 showed increase expansion over Furthermore, clear asymmetrical volume fluxes observed wet that became more symmetrical time when dried.

متن کاملExperimental Study of Coating in a Bottom Sprayed Fluidized Bed
Several investigations have been devoted towards understanding the coating process in fluidized beds. Most of these studies focused on spraying liquid droplets over the bed. However, due to the complexity of these systems, more investigations are still required to quantify the effect of operating conditions on the coating criteria. The present work aims at fundamentally understanding and pr...
متن کاملExperimental Investigation of a Heat Pump Assisted Fluidized Bed Dryer
The drying or dehydration is the controlled heating of food products to evaporate quantified amount of moisture that is originally present in it. Drying of food products is essential to enhance the shelf life of the product without quality losses over an extended period of time. It is an energy intensive process. The fluidized bed dryer with heat pump is one of the efficient method to reduce th...
