Estimation of bubble diameter in gaseous fluidized beds

Abstract

Abstract Bubble size is one of the most important parameters in the design and simulation of a fluidized‐bed reactor. A correlation of the bubble size and growth in fluidized beds of various diameters is developed. A maximum bubble diameter determined from the bubble coalescence is incorporated in the correlation to relate the effect of the bed diameter on the bubble size. Experimental data of bubble size reported are used to develop and test the validity of the correlation. The bubble diameters calculated using this correlation show good agreement with the observed bubble diameters.
