... to minimize the total weight. Various augmentation techniques to improve heat transfer in metal hydride beds, e.g., introduction of aluminum or copper meshes or foams, compacting with carbon fiber, etc have also been tried. Many new materials such as complex hydrides (e.g., alanates, borates), different...

...W. Wu; J. H. Du; Y. R. Lin; L. C. Chow; H. Bostanci; B. A. Saarloos; D. P. Rini This study investigates a V-shaped corrugated carbon foam heat sink for thermal management of electronics with forced air convection. Experiments were conducted to determine the heat sink performance in terms of heat...

...Nesrin Ozalp; Anoop Kanjirakat This study focuses on a technique, referred to as “solar cracking” of natural gas for the coproduction of hydrogen and carbon as byproduct with zero emission footprint. Seeding a solar reactor with micron-sized carbon particles increases the conversion efficiency...

...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...

...Y. R. Lin; J. H. Du; W. Wu; L. C. Chow; W. Notardonato This work focuses on the development of high-effectiveness recuperative heat exchangers using solid and corrugated carbon foam blocks. Characterization tests were conducted on heat transfer and pressure drop for a single carbon foam block...

...Yorwearth L. Jamin; A. A. Mohamad The main objective of this experimental study is to quantify and compare the heat transfer enhancement of carbon foam and aluminum fins in natural convection. The study measures steady state heat transfer from a heated vertical pipe, with and without porous medium...

... objective of this experimental study is to quantify and compare the heat transfer enhancement of carbon foam and aluminum fins. The study measures the heat transfer rate and pressure drop from a heated vertical pipe, with and without porous medium, in forced convection. The largest increase in Nusselt...

... carbon film is roughly 50 – 100 nm , which is three orders of magnitude less than the diameter of a typical optical fiber. The path length of the electromagnetic wave in the film is therefore very small, compared with the fiber radius. The change of orientation of the local coordinates...

...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...
