Determination of permeability for porous media using fractal theory

The precise determination of the permeability for porous media is an important part of the study of heat and mass transfer in porous media. The traditional Taylor formula does not work well in some applications, particularly for heterogeneous porous media. The fractal dimension of the particle diameter distribution b, the section void area fractal dimension d and the spectral dimension ds were counted in a section view of a practical porous media. The Taylor formula was improved by considering the void ratio, the particle diameter and the void connectedness. The new equation for determining permeability is accurate and overcomes the influence of the complex porous media geometry.
