Abstract

Abstract: The single-phase flow through porous media in fracture media under electric field is studied with numerical simulation.A mathematical model describing the flow of single-phase fluid in fracture media under electric field is established based on the equivalent continuum model and the electroosmosis theory,the finite element method for solving the mathematical equations is introduced,three kinds of fracture media models with different fracture apertures are designed,and the effect of electric-field strength,pressure gradient and fracture aperture on flow velocity in fracture media is analyzed respectively in terms of the numerical results.The flow rate can be increased effectively under electric-field,for example,the velocity can be increased by 8.2 times in the fracture media whose aperture is 5×10-5m when electric-field strength is 450v/m,and the ratio of flow velocity under different electrical fields and zero electrical field decays exponentially with pressure gradient increasing.The results indicate that influence of electric field on flow through porous media is more significant with the decreasing in the pressure gradient and the fracture aperture.

Key words: fracture media, electric-field, flow through porous media, numerical simulation, finite element 
