Description
Abstract:
Fractured media can be found in various natural and engineering systems, and the presence of fractures and fracture networks has a significant impact on the flow and transport processes at different scales. However, the complex nature of fractures poses challenges for theoretical modeling and numerical analysis. In this study, we propose a new hybrid upscaling workflow that combines analytical solutions at the continuum scale with fracture network methods. This method aims to preserve the connectivity of the fracture network and account for the interactions between fractures and the surrounding matrix. To validate the effectiveness of the new method, we compared its results with pore-scale simulations. Additionally, we investigated the influence of factors such as permeability, fracture aperture, porosity, and pore structure on the media. Through rigorous accuracy analysis and parameter studies, we assessed the applicability and computational efficiency of the proposed upscaling method.
