“…Certain cellular material properties such as elastic stiffness, effective thermal conductivity, and effective yield strength can be directly related to the properties of the material comprising the cell walls through the relative density (Ashby et al [10]; Lu et al [32]). However, the effective thermal conductivity of metal foam is not only dependent on the relative density and the thermal conductivity of the base material from which the foam is made, but it is also dependent on the actual geometry of the foam due to the conductive pathways through the porous material which are limited to the ligaments of the material (Haack et al [33]; Dai et al [34]). Heat conduction in porous matrices has also been summarized in a number of extensive review articles and books (Kaviany [12]; Alazmi and…”

“…For high porosity metal foams, Calmidi and Mahajan [37] presented a one dimensional heat conduction model that considered the porous medium to be a two-dimensional array of hexagonal cells, whereas Boomsma and Poulikakos [14] proposed a three dimensional model that consisted of tetrakaidecahedron cells with cubic nodes at the intersection of two fibers. This widely used model by Boomsma and Poulikakos [14] was recently shown to be erroneous, corrected and extended by Dai et al [34]. These models involve a geometric parameter that was evaluated using experimental data.…”

Abstract:Recent advances in manufacturing methods open the possibility for broader use of metal foams and metal matrix composites (MMCs) for heat exchangers, and these materials can have tailored material properties. Metal foams in particular combine a number of interesting properties from a heat exchanger's point of view. In this paper, the material properties of metal foams and MMCs are surveyed, and the current state of the art is reviewed for heat exchanger applications. Four different applications are considered: liquid-liquid, liquid-gas and gas-gas heat exchangers and heat sinks. Manufacturing and implementation issues are identified and discussed, and it is concluded that these materials hold promise both for heat exchangers and heat sinks, but that some key issues still need to be solved before broad scale

This chapter is aimed as a concise review, but well-focused on the potentials of what is known as "High-porosity metal foams," and hence, the practical applications where such promising media have been/can be employed successfully, particularly in the field of managing, recovering, dissipating, or enhancing heat transfer. Furthermore, an extensive comparison is conducted between the formulations presented so far for the geometrical and thermal characteristics concerning the heat and fluid flow in opencell metal foams.

Numerical simulation with the Forchheimer flow model and local thermal non-equilibrium model for porous region is performed on forced convective heat transfer in a tube partially filled with metallic foams. Flow and heat transfer of fluid in the hollow region and those of fluid in the porous region are conjugated together via the coupling conditions at porous-fluid interface. A heat flow model is proposed with special numerical treatments employed for non-equilibrium conjugated heat transfer in foam-fluid system. Velocity and temperature profiles in the flow direction are obtained and validated with analytical results. Effects of porosity, pore density, dimensionless interfacial radius and fluid-to-solid thermal conductivity ratio on flow characteristics and thermal performance are examined. Accordingly, the entrance effect is analyzed through the numerical simulation in terms of both flow and heat transfer. The present tube exhibits more excellent heat transfer performance at the expense of moderate pressure drop compared with the tube without porous material. The numerical work is not only developed for forced convection in metal-foam partially filled tube, but can also be extended to similar problem with porous-fluid interface for other porous media with significant thermal non-equilibrium effect.
