Abstract An experimental measurement program was performed to determine thermophysical properties of aluminum-based foam metals. The effective thermal conductivity k e and permeability K were investigated in detail. Experimental facilities were fabricated, and the measurement procedures and methodologies were evaluated. One-dimensional heat conduction was considered to determine k e . The results indicate that k e increases as the porosity ε decreases. However, no noticeable changes in k e were detected from variations of the cell size of the foam metal at a fixed porosity ε. The permeability K is substantially affected by both ε and the cell size. An empirical correlation for the friction factor f is proposed based on the concepts of K and inertial effect.
