Modified correlation for minimum fluidization velocity of low-density particles in inverse liquid-solid fluidized beds
文献摘要：
The minimum fluidization velocity(Umf)is a key parameter for the scale-up of inverse liquid-solid flu-idized beds.Theoretical predictions using common correlations were compared against experimental minimum fluidization velocity measurements of low density(28-638 kg/m3),0.80-1.13 mm Styrofoam particles in a fluidized bed with a height of 4.5 m and 0.2 m diameter.The average absolute relative deviation for the predicted minimum fluidization velocity for particles below 300 kg/m3 was above 40％using the studied common correlations.A modified Wen and Yu correlation was thus proposed based on novel and past measurements with low-density and small-diameter particles,expanding the range for predicting Umf.The new correlation predicted Umf with deviations below 15％for ST028,ST122 and ST300.This modified correlation also improved Umf predictions for comparable particles from a previous study,demonstrating its validity for a larger range of low-density particles.
