Abstract

The connectivity of a complex porous medium is analysed by means of a set of serial sections. From these data, geodesic propagations in different directions provide an estimation of the distribution function of the local tortuosity of shortest paths in the medium while simulations of random walks give estimates of the effective coefficients of diffusion at different scales and of their anisotropy.

Keywords : anisotropy, connectivity, diffusion, geodesic propagation, porous media, simulations, tortuosity
