Abstract

This work describes advances in authors' analysis of free convection in geological porous structures. Results obtained by finite element method for stability analysis and direct 3D computations are compared to experimental measurements in a simple reference configuration: the sloped porous layer bounded by impervious domains. Introduction Natural convection in porous media is of a great practical importance and has been widely studied for years (see Nield and Bejan [1] fora recent bibliography). From an experimental point of view, authors considered a variety of shapes and natures of porous media: horizontal and sloped porous layer heated from below, boxes heated from the sides, hele-shaw cells, cylindrical and spherical enclosures, amsotropic and he
