“…The present model assumptions are: (1) steady state, (2) ideal gas, (3) single phase, (4) laminar flow, and (5) isotropic solid materials, (6) no gravity affect, similar to other researchers [33,34]. The inlet flow is laminar, due to the low flow rates used in the model, as displayed in Table 4, and thus been used in this study, similar to other researchers [22,35,36]. The continuity and Navier-Stokes equations can be expressed as:…”

“…where μ and ρ are the viscosity and density of the fluid and u and p are local velocity and pressure, respectively [22,37]. The density and viscosity of the air, which was used as the fluid in the simulation, are 1.225 kg/m3 and 1.7894 × 10−5 kg/m-s.…”

“…Boomsma et al [21] also simulated flow through OPCF using the tetrakaidecahedron cell. Xu et al adopted the tetrakaidecahedron model to systematically investigate the flow patterns in porous media and the relationship between fluid flow parameters and foams structure characteristics [22]. However other researchers such as Ozmat et al [23] [16,20].…”

In this article, the structural characterization of chemical vapor deposition (CVD) nickel metal foam is presented. Scanning electron microscope and post image processing were used to carefully analyze the surface of the nickel metal foams. Data on foam unit cell, ligament thickness, projected pore diameter, and averaged porosity was obtained. Unit cell and projected pore diameters of CVD nickel metal foam possess Gaussian-like distribution. Characteristics of pore structure and its effect on permeability in Darcian flow regime were analyzed. The relations between the permeability, pore size, and porosity are presented. Present and previous data are compared with these relations. Measurement results indicate that the permeability or the viscous conductivity of the CVD processed metal foam is affected not only by the pore size, and porosity but also by the ligament structure.

A three-dimensional numerical model is proposed to determine heat and fluid flow characteristics in metal foams. A series of full three-dimensional numerical calculations was performed to reveal complex three-dimensional velocity, pressure and temperature fields within three-dimensional porous structures of the metal foams. These numerical results are processed to obtain the macroscopic characteristics such as the permeability, inertia, dispersion and interstitial heat transfer coefficients. An effective pore diameter concept has been proposed to correlate the resulting heat and fluid flow characteristics with available empirical correlations.
