Axial Thermal Dispersion Conductivity of Open-Cellular Porous Materials

摘要

The axial thermal dispersion coefficients of open-cellular cordierite-alumina foams, γ_a, were originally determined by the inverse analysis of steady-state axial temperature profiles within the porous media. It is found that γ_a is much greater than the previously reported radial thermal dispersion coefficients of open-cell foams and packed beds and the known axial thermal dispersion coefficients of packed beds.
