A Growth Model for Porous Sedimentary Rocks
arXiv:cond-mat/9708100 · doi:10.1016/S0921-4526(98)00431-1
Abstract
A growth model for porous sedimentary rocks is proposed, using a simple computer simulation algorithm. We generate the structure by ballistic deposition of particles with a bimodal size distribution. Porosity and specific surface area are calculated varying the proportion of small and larger particles. Permeability and its variation with porosity are studied. The fractal nature of the pore space is also discussed.
