ExPeriments were carried out in a cylindrical fluidized bed of 104 mm diameter and 1500mmheight,with water as fluidized medium. The axial dispersion coefficients were obtained bymeasuring the RTD at different fluid rates for different particle systems and were correlated.Inaddition ,based on the variation of ε, a ctiterion for the demarcation of particulate fluidization and aggregative fluidization was deduced(eq.4), as shown by eqs.(1)-(3).
