The effect of microstructure on the permeability of metal foams

Metal foam (MF) is a superior material with complex structure made from different kinds of materials manufactured using novel technology. Due to its several unique properties with high porosity and high surface area, it finds use in wide area of engineering, such as energy absorbers, filters, heat exchangers etc. The structures of metal foam are very intricate and irregular and it is very difficult to accurately predict the impact of microstructure on pressure drop. Most of the recent literature studied permeability at low velocity range. Thus the present study was carried out to have better understanding of permeability for greater velocity range to suit industrial applications. The necessary equipment was designed and built for this purpose. (Abstract shortened by UMI.)...
