On a numerical method to compute flow in complex 3D geological fractured porous media
Abstract
This communication focuses on numerical techniques to compute flow in complex 3D geological fractured porous media, where water can flow both in the rock matrix and in the fractures. This study is an extension of the model of 2D fractured porous media proposed in [C. Alboin, et al. Modeling fractures as interfaces for flow and transport in porous media (2002) and N. Frih, et al. Modeling fractures as interfaces: a model for Forchheimer fractures (2008)]. It also uses techniques to compute flow in 3D fractures network [J. Erhel, et al. Flow simulations in three-dimensional discrete fracture networks (2009) and G. Pichot, et al. A mixed hybrid mortar method for solving flow in discrete fracture networks (2010)] or 3D rock matrix. We present the model and the numerical method we propose. An overview of the software development in the H2Olab platform is also proposed.
