摘要：

The critical gas velocity for suspension of solid particles was studied in 200-mm- and 385-mm-i.d. bubble columns. The terminal settling velocity was varied in the range 8.2-290 mm/s, and the volume of solids per unit cross-sectional area of the column was varied from 5.8-80 mm (0.05-5% by volume). The effects of sparger design and the column height have been investigated. A rational correlation has been proposed.
