Effective thermal conductivity of high porosity fibrous metal foams

摘要

The effective thermal conductivity of metal foams made of aluminum was experimentally studied by using both air and water as the fluid phases. Based on the experimental data, an empirical correlation was developed. A theoretical model was also derived based on the hexagonal structure of the metal foam matrix. The model was found to match extremely well with the experimental results for both air and water for an area ratio value of 0.09.
