Abstract

GAS–SOLID FLUIDIZED BED REACTORS HAVE MANY INDUSTRIAL APPLICATIONS AND HAVE BEEN STUDIED BY MANY RESEARCHERS. IN THIS STUDY, THE 2D HYDRODYNAMICS OF FLUIDIZED BED WAS INVESTIGATED BY USING CFD ANALYSIS. TO PERFORM THE SIMULATION OF FLUIDIZED BED, THE TWO-FLUID MODEL (TFM) BY THE KINETIC THEORY OF GRANULAR FLOW (KTGF) WAS USED TO DESCRIBE THE SOLID PARTICLES AS CONTINUUM PHASE. ALSO FOR THIS SYSTEM (DENSE GAS-SOLID FLUIDIZED BED), AN ALGEBRAIC GRANULAR ENERGY-BALANCE EQUATION IS PROPOSED TO DETERMINE THE GRANULAR TEMPERATURE INSTEAD OF SOLVING THE FULL GRANULAR ENERGY BALANCE EQUATION. THIS SIMPLIFICATION DOES NOT LEAD TO DIFFERENT RESULTS, BUT SIGNIFICANTLY REDUCES THE COMPUTATIONAL EFFORT OF THE SIMULATION. THE COMPUTATIONAL FLUID DYNAMICS SIMULATION RESULTS WERE COMPARED TO BUBBLING FLUIDIZED BED CONTAINING THE AVERAGE SPHERICAL GLASS BEADS OF 275 MICRON IN DIAMETER. THE RESULTS OF THIS SIMULATION FOR LOCAL VOIDAGE AND LOCAL SOLID VELOCITY ARE IN A GOOD AGREEMENT WITH THE EXPERIMENTAL DATA AND SHOW A SUITABLE TREND IN COMPARISON WITH THE THEORETICAL FINDINGS. WHILST THE SUPERFICIAL GAS VELOCITIES WERE 0.1, 0.38 AND 0.48 M/S.
