Transport Phenomena in Solids with Bidispersed Pores
Existing analyses for transport phenomena in bidisperse porous media assume that the microparticles act as uniformly distributed point sinks. This study provides an analysis which determines under what conditions the point sink approximation is valid. For random packing, the concentration field inside a pellet is described by its ensemble average, i. e. , the average over all possible ways in which the microparticles can be packed into the pellet. For these averaged quantities, the authors formulate the transport equations for a solid with bidisperse pores which provide the criteria of validity of the point sink approximation.
