| Abstract: |
| There are various mathematical and mechanical models,based on the continuum mechanics or discrete cracks,for the flow through fractured porous media.Inspired by the physical interface,a new finite crack continuum mechanics model is proposed,which can be used for macroscopic pore-fracture-porous media.As a dual porosity/permeability model,this model converts the low-dimensional fluid flow on curves and surfaces into a three-dimensional flow field.The three-dimensional flow field is coupled with that of the porous media,and a universal mathematical model is built,including governing transport equations and initial and boundary conditions.This approximate model provides a novel idea for numerical calculation methods,such as meshless particle-based methods (e. g. ,smoothed particle hydrodynamics),that are inconvenient to solve multiple-dimension problems. |
