... the charging time at the expense of additonal system weight incurred due to larger fin area. Since bed thickness is the dominant factor in deciding the total system weight, thinner beds for a given quantity of alloy are heavier. A variety of carbons like activated carbon, carbon nanotubes (CNT...

...Patrick T. Garrity; James F. Klausner; Renwei Mei The air side heat transfer performance of three aluminum foam samples and three modified carbon foam samples are examined for comparison with multilouvered fins often found in compact heat exchangers. The aluminum foam samples have a bulk density...

...Qijun Yu; Brian E. Thompson; Anthony G. Straatman A unit-cube geometry model is proposed to characterize the internal structure of porous carbon foam. The unit-cube model is based on interconnected sphere-centered cubes, where the interconnected spheres represent the fluid or void phase. The unit...
