摘要: A systematic numerical study of the macroscopic electrical conductivity σ vugular porous media has been conducted by solving Laplace equation. The structure these bimodal is characterized micro and macroporosities macro correlation lengths. overall function analyzed. It shown that mainly depends on total porosity, very little other parameters. Moreover, similar results are obtained when microporous medium considered as a continuum. Finally, predictions compared to experimental data for formation factor thermal limestones; agreement good in first case, excellent second.
