Analysis of heat transfer through multi-layers wall including air and porous layers

In this study, heat transfer through a multi-layer ceramic furnace wall was analyzed, the study concentrates on the analysis of an air layer inside the wall, and moister transport from moist porous layer to adjacent air in the air layer. By considering several porosity values ranging from 0.1 to 0.9, the effect of porosity on the total heat transfer thought the wall and the effective thermal conductivity was concluded. this study concludes that increase porosity in the porous layer will reduce the total heat flux through the wall and reduce the effective thermal conductivity in the air and porous layers.
