Abstract In this paper, a new model is proposed to predict the permeability of porous
media. This model introduces the Euler-Poincaré Characteristic (Euler Number), a
parameter that reflects the connectivity of porous media. Using fractal and
percolation theory, we establish a permeability model as a function of critical
radius, porosity and Euler number. In order to relate the result to the Euler
number, we introduce the Connectivity Function to calculate the critical aperture
in the percolation theory, then calculate the percolation threshold value, and
establish the relationship between the percolation threshold and the Euler
number. The validity of the model is… More >
