Metal foams as novel materials for air-cooling heat exchangers
High-porosity metal foams have thermal, mechanical, electrical, and acoustic properties making them attractive for various engineering applications. Due to their large surface-area-to-volume ratio, tortuous flow path, and relatively high thermal conductivity they are being considered for a range of …

A geometric study of liquid retention in open-cell metal foams
Open-cell metal foams show promise as an emerging novel material for heat exchanger applications. The high surface-area-to-volume ratio suggests increased compactness and decrease in weight of heat exchanger designs. However, the metal foam structure appears conducive to condensate retention, which …
