TLDR
In this article, a pore scale numerical simulation of heat and mass transfer in several foams is realized using 3D geometry from X-Ray tomographic images and fully characterized using the iMorph software.Abstract:
Pore scale numerical simulation of heat and mass transfer in several foams are realized. 3D geometry is reconstructed from X-Ray tomographic images and fully characterized using the iMorph software. Microscale quantities such as temperature, pressure and velocity fields are computed using commercial software (StarCCM+) based on finite volume method. Macroscale properties are then deduced from numerical data and compared to experimental ones. Impact of foam topology and material as well as fluid nature (Fluid dynamic viscosity, solid thermal conductivity [[ellipsis]]) on transfer properties are systematically studied. We discuss correlations of these results with geometrical characteristics of the samples by scaling the metal foam in order to change pore diameter.Copyright © 2010 by ASMEread more

Pore-scale simulation of forced convection heat transfer under turbulent conditions in open-cell metal foam
TL;DR: In this paper, the effects of porosity, PPI, and closed pores on the pressure drop and heat transfer properties were investigated, and the results indicated that the porosity was more sensitive to porosity than PPI.
