Effect of Co-axial Rod-promoter on the Pressure Drop in a Batch Liquid-solid Fluidized Bed

Abstract

This paper deals with experimentation conducted to obtain pressure drop and bed expansion data in liquid-solid fluidized beds under varying conditions. The rate of flow, bed height, particle size and density have been altered and the resulting pressure drop and the bed expansion have been measured. The data have been correlated in terms of Euler number. Expressions relating the Euler number with system parameters have been obtained in case of beds with and without promoter. The predicted and experimental values of Euler number have been found to agree fairly well.
