Studies on the Hydrodynamics of Fluidized Layers III. Calculation of Layer Expansion in Systems Fluidized With a Liquid

Abstract

The equations for the calculation of the void fraction of layers fluidized with a liquid, most widely known from literature, and those derived from the first paper of the series are briefly described. The equations are transformed to a form which can readily be applied in practice even in the case of porous particles. The mean values of the "constant coefficients" of the equations, and the dependence or independence of the different "constants" on the various parameters was studied. The calculation methods are evaluated by the comparison of void fraction values determined experimentally and calculated by the proposed equations.
