WebJan 10, 2013 · The heat is transmitted through the tube wall and the graphite foam porous cell surface and finally it is dissipated to the air. There are many parameters to describe the configuration of the graphite foam heat exchanger. WebA local thermal non-equilibrium analysis of heat and fluid flow in a channel fully filled with aluminum foam is performed for three cases: (a) pore density of 5 PPI (pore per inch), (b) pore density of 40 PPI, and (c) two different layers of 5 and 40 PPI. The dimensionless forms of fully developed heat and fluid flow equations for the fluid phase and heat …
