Abstract
Porous materials play an important role in several practical and technological applications. They provide complex pathways for different transport phenomena that can be performed in the pore and solid phase. A deep understanding of the material’s behavior allows the enhancement of different properties. Open pore network modeling (OpenPNM) appears as a powerful tool to analyze different transport phenomena in these complex materials. In the current study, a three-dimensional volume representing a digitally generated gas diffusion layer (GDL) has been analyzed from an energy transport point of view. Three correlations describing the behavior of the effective thermal conductivity as a function of the porosity have been proposed.
