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,
design 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.
