Abstract

This paper, second in a series of two, examines the effect of liquid addition to beds of gas fluidized porous and/or non-spherical particles. It is demonstrated that a pore network in even cohesion-sensitive particles delays stickiness upon the addition of liquids. A number of non-volatile silicone oils ranging in viscosity from 0.005 to 34.6 Ns m-2, as well as water, were added to a range of Geldart B and D particles in a conventional gas-solid fluidized bed. Liquid loadings of up to in excess of 220% (wet basis) have been tested. Capillary forces dominate the behaviour of Geldart B particles over a range of conditions, while Geldart D particles are somewhat influenced by viscous forces.
