Abstract
The behavior of bubbles in a circulating gas-liquid-solid fluidized bed was investigated in a column of 25.4 mm ID and 5 m height with glass beads of 5 different sizes by using a bore scope. The distribution of bubble size followed the logarithmic normal distribution law. At high liquid velocity the effects of particle size and solid concentration on volume-surface mean diameter of bubbles were negligible because of liquid turbulent motion.
