Abstract

Mass and energy transfers processes in partially saturated open porous media is a research topic that finds many applications in structures field. The heterogeneous and random nature of the microstructure of porous materials and their transfer properties make essential the recourse to probabilistic approaches. A first step in this direction was to extend the modelings to take into account the not correlated statistical and spacial variability for physical parameters governing the processes of transfer. This work was the object of many publications and articles. The following part of the work consists in carrying out probabilistic analyses. We will then focus on the influence of the space correlation of the parameters on the convergence of statistic elementary volumes (SEV: achievements obtained by random realizations) towards representative elementary volumes (REV). The effect of the space correlation is studied by considering the length of correlation
