Fluid flow pattern, minimum spouting velocity and pressure drop in spouted beds

Abstract

Abstract This study extends the theory of Mamuro and Hattori to beds of less than the maximum spoutable height. The new model gives predictions for the fluid flow pattern, minimum spouting velocity and spouting pressure drop which are in agreement both with experimental data on beds spouted with air and water (obtained in this study) and with literature data. A correlation for H m in water spouted beds of spherical glass particles is also presented.
