abstract = {<p style="text-align: justify;">In this paper Lattice Boltzmann Method (LBM) has been used in order to
perform Direct Numerical Simulation (DNS) for porous media analysis. Among the
different configurations of porous media, open cell metallic foams are gaining a key
role for a large number of applications, like heat exchangers for high performance
cars or aeronautic components as well. Their structure allows improving heat transfer
process with fruitful advantages for packaging issues and size reduction. In order
to better understand metallic foam capabilities, a random sphere generation code has
been implemented and fluid-dynamic simulations have been carried out by means
of a kinetic approach. After having defined a computational domain, the Reynolds
number influence has been studied with the aim of characterizing both pressure drop
and friction factor throughout a finite foam volume. In order to validate the proposed
model, a comparison analysis with experimental data has been carried out too.</p>},
