□numerical simulation for 4 different ratios of initial bed heights (H) to base diameter (D), were performed□nviz. 0.□, 1, 2 and 3. Glass beads of density 2□0Okg/m~3 and with an average diameter of □□0□m were used for all the simulations. Simulations were performed using the commercial CFD software, STAR-CCM□. The minimum fluidization velocity was identified by measuring pressure drop across the entire domain and found to remain same for all the above mentioned ratios. Comparison between experiment□1 □and simulation is done.
