Numerical Experimental Research of Effect on Fractured Porous Media Equivalent Permeability
Firstly, the mathematical model were established about fractured porous media seepage. Secondly, in the platform of COMSOL Multiphysics, making fluid mechanics and hydrodynamics combined. Thirdly, the experiment was designed according to four factors and four levels orthogonal table. Finally, changes in porosity, pressure gradient, crack width and crack angle due to simulated the change regularity of equivalent permeability in media. The results shown: porosity has the most significant impact on the equivalent permeability;the equivalent permeability increased with the increment of porosity and crack of fractured porous media;the equivalent permeability decreased with the increment of pressure gradientand crack angle of fractured porous media.
