Wpływ niejednorodności struktury ośrodka porowatego typu włóknistego na współczynnik przepuszczalności Darcy'ego
A model of porous media consisting of random distribution of parallel fibers is proposed to account for nonuniform fiber spacing in a real porous media. Basing upon a generalized cell model of hydrodynamics, the tensor of permeability of this anisotropic media is determined. The components of permeability tensor contain two parameters which are determined basing upon some chosen experimental data by mean of the least squares approximation.
