Energy conservation and heat dissipation by maximizing convection heat flow in a channel with particulate media

S.M.Prabhu, Abbas Moinudeen

Here we discuss the experimental results for flow due to gravitational porous multiblock porous media. These are applied in Electronic packages (Linear and hybrid Integrated Circuits).ABrinkman extended Darcy model and a semiheuristic energy model is obtained by relaxing the local thermal equilibrium(LTE)assumption are adopted. Aluminiumfoamsamples of different pore sizes(5-60PPI) and porosities(0.8-0.99) were used to illustrate the effects of metal foam geometry on heat transfer. Energy concentration is done by porous cavities in the prous media for energy savings and enrgy distribution.
