This book provides a user-friendly introduction to convection in porous media, such as fibrous insulation, geological strata, and catalytic reactors with applications in building insulation, energy storage, nuclear-waste disposal, coal and grain storage, chemical reactor engineering, groundwater flow, and convection in snow. The presentation is self-contained, requiring only routine classical mathematics and the basics of fluid mechanics and heat transfer. 264 illus.
