This book presents in a self-contained fashion a series of studies on flow and heat transfer
in porous media in which distinct energy balances are considered for the porous matrix and for
the permeating fluid. Detailed mathematical modeling is presented considering both volume and
time averaging operators simultaneously applied to the governing equations. System involving
combustion in the gaseous phase moving bed and double-diffusion mechanism are analyzed.
Numerical results are presented for each case. In the end this book contains the description
of a tool that might benefit engineers in developing and designing more efficient thermal
equipment.
