摘要：

Hydrodynamic studies are reported on six different materials, spouted and spout-fluidised with air in a column of square cross-section, using nozzles of five different sizes. Correlations for minimum spout-fluidised flow rate in cylindrical columns were investigated for this geometry. New correlations for predicting the minimum spouting velocity and the minimum spout-fluidising velocity are developed. The velocity profile in the bed agreed well with the observations of Lim and Grace [1], and Mamuro and Hattori [2].
