β¦ Synopsis
A study of sluggmg flmdlzed beds has been camed out m four tubes ranging m size from 5-30 cm I d usmg particles havmg mean sizes 55-3380 pm and densities 0 85-2 8 gm crne3 For all but the smallest column neither particle size nor size dlstnbutlon had any effect on slugging Equations are presented which enable us to calculate (a) The height and gas velocity at which sluggmg commences, (b) The distance above the dlstnbutor at which further slug coalescence ceases, and (c)The numerical value of the stable slugging frequency which 1s thereafter attained

Computational Fluid Dynamics (CFD) modelling has been used to simulate a liquid fluidized bed of lead shot in slugging mode. Simulations have been performed using a commercial code, CFX4.4. The kinetic model for granular flow, which is already available in CFX, has been used during this study. 2D ti
## Abstract Pressure fluctuations within a bed of Type D particles (coarse sand, long grain rice, red spring wheat, 10 mm glass beads, pearl barley and whole peas) were measured at various bed heights. Analysis of the pressure fluctuation profiles leads to correlations that predict the minimum slug
