Dual porosity DRM formulation for flow and transport through fractured porous media

摘要

The main objective of this work is to develop a model for flow and solute transport in fractured porous media based on the dual porosity approach and the Dual Reciprocity Method. The developed model is compared to the results obtained using the equivalent continuum model and the discrete fracture/non-homogeneous model. The comparison is performed for a square porous domain with regular mesh of three parallel fractures combined with a further three fractures perpendicular to the first ones. The results helped to draw some conclusions in respect to the similarity of potentials as well as fluxes for the different methods. In this research the Boundary Element Dual Reciprocity Method scheme (BE DRM) has been used, in combination with the dual-porosity model.
