This book provides a user-friendly introduction to convection in porous media such as fibrous insulation geological strata and catalytic reactors. The presentation is self-contained requiring only routine classical mathematics and the basic elements of fluid mechanics and heat transfer. It will thus be of use not only to researchers and practicing engineers as a review and reference but also to graduate students and others just entering the field. The Third Edition includes nearly 1000 new references and covers: convection in deforming porous media designed porous media the theory of deformable media modeling viscous dissipation in hyperporous media and more.
