Published Online: February 13, 2012
... properties of graphite foams are oversimplified. In particular, it has been found that the dispersion conductivity is not well characterized using the Péclet number alone, rather the Reynolds and Prandtl numbers must be considered as separate influences. Additionally, the convecting velocity modification...

...Pamela M. Norris; Justin L. Smoyer; John C. Duda; Patrick E. Hopkins Due to the high intrinsic thermal conductivity of carbon allotropes, there have been many attempts to incorporate such structures into existing thermal abatement technologies. In particular, carbon nanotubes (CNTs) and graphitic...

...Robert J. Moffat; John K. Eaton; Andrew Onstad Metallic and graphitic open-cell foams are being used or proposed as extended surfaces (fins) in heat sinks for electronic cooling and compact heat exchangers for aircraft applications. Three parameters must be known to calculate the heat transfer...

...Nihad Dukhan In certain contemporary technologies, porous media with high solid-phase conductivity are impregnated with low-conductivity fluids, e.g., metal and graphite foam cooled by air. For such cases, an approximate analytical model for the developing heat transfer inside a two-dimensional...

...Randy D. Weinstein; Thomas C. Kopec; Amy S. Fleischer; Elizabeth D’Addio; Carol A. Bessel To improve the thermal performance of phase change materials (PCMs), graphite nanofibers were embedded into a paraffin PCM. The thermal effects of graphite fiber loading levels ( 0 – 5 wt % ) and graphite...
