Abstract

Liquid Telocity distribution was measured in a bubble column 5.5 m in diameter and approximately 7 m in liquid height. Liquid flow was upward in the column center and downward near the wall. The upward velocities were from 52 to 115 cm/sec in the superficial gas velocity range from 2.4 to 8.5 cm/sec.
The liquid velocity distribution is analyzed by a circulating flow model. Values of the turbulent viscosity-the parameter of the model-are in the range from 3000 to 4000 g/cm • sec. These values agree well with those estimated by an empirical formula for turbulent viscosity proposed by Miyauchi and Shyu for smaller-diameter bubble columns.
