Simulation of electrical-conduction and filtration processes in porous media

Results of simulation of electrical-conduction and filtration processes in porous media have been reported. For better visualization and simplification of the analysis of the results obtained, simple model distributions of pore sizes with the patterns of a triangle, rectangle, semiellipse, etc., have been used. The porous medium has been simulated in terms of a capillary lattice model, which represents a three dimensional cubic lattice of capillaries the sizes and number of which are selected according to a preset pore size distribution. The data obtained reflect the general regularities of the influence of the pore structure on the transfer processes, show the interrelation between the parameters characterizing these processes, and illustrate the potential of the capillary-lattice model for describing the properties of porous media.
