The relationship of geometrical parameters with thermal properties such as effective thermal conductivity is critical for conductive heat transfer in metal foams. We have realized different virtual isotropic structures of tetrakaidecahedron shape having circular, square, hexagon, diamond and star strut shapes with various orientations using CAD modeling. The range of solid to fluid phase conductivity ratios (λs/λf) studied is from 10 to 30,000 for porosity range 60–95%. At pore scale, 3-D direct numerical simulations were performed to calculate effective thermal conductivity, λeff in local thermal equilibrium condition. A database of 2000 values of effective thermal conductivity is generated.
