Steady and oscillatory analysis of porous catalysts in fluidized beds



In this paper, we consider the steady /oscillatory flow field within a porous particle contained in a fixed or fluidized bed, in which the spherical porous particle is placed in a spherical envelope of fluid. Stokes equations are employed inside the fluid envelope and Brinkman/Darcy equations are used inside the porous region. We compute drag force acting on the particle and hence the overall bed permeability of the bed. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
