minimum spouting velocity and maximum aerating velocity of a draft tube spouted bed with aeration were studied in a 92 mm-I. D. plexiglass column. Experiments were carried out by using four experimental particulate materials and air as the medium for spouting and aeration. A correlation
derived by regressing experimental data
was proposed for predicting the minimum spouting velocity and the maximum aerating velocity of a draft tube spouted bed with aeration.
