Abstract
The material characterization of open-cell aluminum foam in terms of heat
transfer is presented. A one-dimensional heat transfer model for the combined
convection and conduction in the foam is summarized. The model uses the foam
parameters that are usually reported by the manufactures such as: the surface
area, the relative densities, the ligament diameters and number of pores per inch.
The model predicts the temperature profile in the foam. The model was applied
successfully to a sample of aluminum foam having ten pores per inch and was
verified by direct experiment. Excellent agreement between the predictions of
the model and the experimental data was obtained. The assumption of a onedimensional
heat transfer was validated. The effect of the air flow rate on the
heat transf
