Effective permeability and thermal conductivity of open-cell metallic foams via homogenization on a microstructure model

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

“…The original version of the model of Singh and Kasana [47], Eq. (19), developed for metal foams, gives a MSE of 0.340 and 0.150 for air and water, respectively. If the parameter F is written as: for water.…”

“…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.…”

The effective thermal conductivity of open cell replicated aluminium metal sponges

“…The most common type of transient measurement is the Transient Plane Source technique (TPS) [25,26], where a single element acts as both temperature sensor and heat source . It has been widely used to measure the ETC of porous materials [6,12,23]. The TPS element is positioned between two samples with similar characteristics and measures the instantaneous temperature gradient with time [6,25,26].…”

Advanced numerical method for generation of three-dimensional particles and its application in microstructure-based simulation of fatigue behavior

“…Stiénon and coworkers [14] used micro-tomography to perform simulations on one CaO inclusion in order to assess the sensitivity of particles shapes and interfaces friction laws. Laschet et al [15] also work on metallic foams reconstructed from X-ray microtomography to perform a multiscale approach. However, in both cases, the meshing method applied was not precisely described.…”
