Opis

Convection in porous media has a large field ofapplication. Firstly, this book presents ananalytical and numerical study of the generation andflow of methane gas through a layer of porous mediumimpregnated with solid clathrate hydrates. Later,design with constructal theory is addressed. Westart studying the fundamental problem of maximizingthe thermal contact between an entire heat-generatingvolume and a pulsating stream of coolant that bathesthe volume. A series of examples in which the globalperformance of flow systems is optimized subject toglobal constraints is also presented. The textcontinues describing a hierarchical strategy todeveloping the optimal internal structure of a roundheat-generating body cooled at its center with thehelp of optimally distributed inserts ofhigh-conductivity material. Finally, it considersthe fundamental problem of squeezing into a fixedvolume the highest heat transfer rate that can bemade to occur between two streams at differentinitial temperatures.
