Effect of sand sizes on the fluidization behavior in circular and rectangular columns
The effect of different sand sizes on the fluidization behavior in circular and rectangular columns was investigated. Three groups of sands with different mean diameters (Sand Sieve No. 10/20 (dpmean = 0.870 mm), Sand Sieve No. 20/30 (dpmean= 0.670 mm) and Sand Sieve No. 30/60 (dpmean= 0.340 mm) wer...

The effect of different sand sizes on the fluidization behavior in circular and rectangular columns was investigated. Three groups of sands with different mean diameters (Sand Sieve No. 10/20 (dpmean = 0.870 mm), Sand Sieve No. 20/30 (dpmean= 0.670 mm) and Sand Sieve No. 30/60 (dpmean= 0.340 mm) were used. The. experiment was conducted using circular and rectangular columns of same the cross-sectional area.
