Convection in Channels and Porous Media

Convection in porous media has a large field of application. Firstly, this book presents an analytical and numerical study of the generation and flow of methane gas through a layer of porous medium impregnated with solid clathrate hydrates. Later, with constructal theory is addressed. We start studying the fundamental problem of maximizing the thermal contact between an entire heat-generatingvolume and a pulsating stream of coolant that bathes the volume. A series of examples in which the global performance of flow systems is optimized subject to global constraints is also presented. The text continues describing a hierarchical strategy to developing the optimal internal structure of a round heat-generating body cooled at its center with the help of optimally distributed inserts of high-conductivity material. Finally, it considers the fundamental problem of squeezing into a fixed volume the highest heat transfer rate that can be made to occur between two streams at different initial temperatures.
