Microtomography-based CFD Analysis of Transport in Open-Cell Aluminum Metal Foams

On the effective thermal conductivity of aluminum metal foams: Review and improvement of the available empirical and analytical models

“…A slight improvement can be obtained by modifying Eq. (23a) in the following way: (41) while keeping Eq. (23b) and Eq.…”

“…At the moment, a significant effort is devoted to describing the foam structure in a more realistic way: from this perspective, X-ray computed microtomography (μ-CT) appears a promising and appealing approach to be coupled to numerical simulations. The literature includes several works dealing with μ-CT, not only limited to metal foams or thermal conductivity estimations [1,3,[13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45]. The literature offers a wide set of analytical and empirical correlations for the estimation of the effective thermal conductivity of metal foams.…”

Pressure drop in flow across ceramic foams—A numerical and experimental study

“…This is a common issue that was 520 previously reported in other works (Große et al, 2008(Große et al, , 2009) and can be explained by the features of the formation process of the foam specimen (Scheffler and Colombo, 2006). In contrast, in the case of metallic foams it was reported that the pressure drop is lower in one direction (Ranut et al, 2014).…”

“…Another case concerned research aimed at an electromagnetic improvement of the alloy filtration(Kennedy et al, 2013), using the COMSOL module based on FEM. Only 2D flow simulations were carried out, however Ranut et al (2014). performed a full 3D simulation of combined heat and fluid flow across 10ppi, 20ppi and 30ppi metallic foams.…”

Computational evaluation of effective transport properties of differential microcellular structures

“…This approach 26 enabled an understanding of the dependence of flow permeability on the pore‐structure‐related properties (most importantly, the pore diameter openings) of the porous structures. The results of μCT‐based CFD modeling and simulation of fluid transport across differential open‐celled aluminum foams were reported in Reference 27 for laminar flow regimes.…”
