    Notes: Transport of small molecules in heterogeneous materials can be an important factor in many engineering and biological applications. This study focuses on the diffusion of cellular nutrients in an immobilized cell system. A Monte Carlo simulation technique is used to describe the diffusion of small molecules in a variety of simulated cellular structures. Diffusivity predictions are in close agreement with experimental values as well as with theoretical bounds reported in the literature. It is revealed that effective diffusivities are highly dependent on the diffusivities of the species in the various phases and on the volume fraction of cells. The spatial arrangement of the cells, however, has no apparent effect on the predicted diffusivity for the range of conditions investigated.

    Notes: A simple correlation method has been developed to predict effective diffusivities of small molecules in heterogeneous materials such as immobilized cell systems. This correlation uses a single diffusivity measurement at one cell volume fraction to predict diffusivities for any other volume fraction of cell. The method has been applied to 20 sets of published diffusivity measurements in immobilized cell systems and accurately predicts affective diffusivities of molecules for the full range of cell fractions. It may also be used to predict effective diffusivities in heterogeneous materials in which the diffusivity of a molecule in each phase and the volume fraction of each phase are known. © 1996 John Wiley & Sons, Inc.
