RÉSUMÉ

Computational modeling of an idealized rock fracture under confining stress was conducted. A combination of computational fluid dynamics and finite element (FE) models was used in the analysis of the undeformed and deformed fracture. The FE analysis incorporated elastic-plastic material nonlinearities. The effective permeability of the fracture was calculated using Darcy's law. The simulation results and the computed permeability of the fracture were compared with the experimental data. It was shown that the effective permeability of the idealized rock fracture varied nonlinearly with the confining stress. The permeability results of the model agreed qualitatively with the experiments; however, quantitative discrepancies were found.
