(EN)The present invention provides a method for calculating the permeability of a porous medium with respect to a laminar flow and a turbulent flow in consideration of geometrical characteristics and friction loss characteristics. A method for calculating the permeability of a porous medium according to one embodiment of the present invention comprises: a step of providing the porosity of pores of a porous medium; a step of calculating a hydraulic diameter of the pores of the porous medium; a step of providing a friction coefficient of the porous medium; a step of calculating the tortuosity of the porous medium; and a step of calculating the permeability of the porous medium using the porosity, the hydraulic diameter, the friction coefficient and the tortuosity.
(FR)La présente invention concerne un procédé de calcul de la perméabilité d'un milieu poreux par rapport à un écoulement laminaire et un écoulement turbulent en tenant compte de caractéristiques géométriques et de caractéristiques de perte de frottement. Selon un mode de réalisation de la présente invention, un procédé de calcul de la perméabilité d'un milieu poreux comprend : une étape consistant à obtenir la porosité des pores d'un milieu poreux ; une étape consistant à calculer un diamètre hydraulique des pores du milieu poreux ; une étape consistant à obtenir un coefficient de frottement du milieu poreux ; une étape consistant à calculer la tortuosité du milieu poreux ; et une étape consistant à calculer la perméabilité du milieu poreux au moyen de la porosité, du diamètre hydraulique, du coefficient de frottement et de la tortuosité.
