Modeling microheterogeneous cell models

In all the cellular models described, the cells throughout the medium were initially uniform. A microheterogeneous cell model has recently been developed, where the cells have varying initial properties (Hwang et ai, 1997). In such a model, the structure of the reaction medium is stochastic, and the heterogeneity of the reactant medium is considered explicitly. For example, the structure can be described as a regular two-dimensional matrix of circular cylinders (with nominally flat sides) in contact, with a number of cylinders randomly removed until the ratio of the voids to total volume equals the porosity (Fig. 23a). The cylinder diameter is assumed to be similar to the particle diameter. [Pg.133]
