5. Conclusion

Although heat transfer with phase change in porous media is still the subject of a great deal of research work, with increasingly complex or new problems being considered (very low or very high permeability media, coupled transfers, nanothermal, etc.), engineers have a body of knowledge (results and models) and experimental and numerical tools enabling satisfactory predictions to be made for a large number of problems. From both theoretical and experimental points of view, however, the exploitation of this knowledge often comes up against difficulties not only in determining the actual transfer properties, but also in measuring a large number of variables locally. Progress in characterization tools (tomography, etc.) and numerical computation (high-performance computing) points to significant future advances.

Finally, certain aspects of scale change are far from...
