Prediction of pressure drop for a conical fixed bed of spherical particles in gas—solid systems

Abstract

The object of this work was to develop an equation to predict the pressure drop in conical beds of spherical particles. Work reported earlier is limited to a single cone angle in liquid—solid systems, whereas in the present study cone angles of 10°, 30°, 45° and 60° were used to predict the pressure drop for fixed beds. Air was used as the fluid medium and the bed consisted of spherical glass particles of various sizes. The constants C1 and C2 were determined and were used to calculate pressure drop values. Experimental and theoretical values of pressure drop were compared and the mean and the standard deviation were calculated.
