Thermal conductivity improvement of phase change materials/graphite foam composites

Rigid polyurethane foams incorporated with phase change materials: A state-of-the-art review and future research pathways

“…melting and solidification. In order to conquer this problem, based on the knowledge that both carbon foam and graphite foam have low density, a large specific surface area and high thermal conductivity of their skeleton, a series of experimental or numerical investigations were conducted on the composites of PCM and carbon foam or graphite foam to increase the thermal conductivity [64][65][66][67]. Compared with carbon foam or graphite foam, the thermal A c c e p t e d M a n u s c r i p t conductivity of PU foam is significantly lower -nearly ten times lower than that of paraffin waxtherefore the combination of an organic PCM and PU foam will further hinder heat transfer in the PCM.…”

Numerical investigations of using carbon foam/PCM/Nano carbon tubes composites in thermal management of electronic equipment

“…This assumption is supported by [20,25] where the convection motion is neglected due to the small size of the pores. Also the assumption of neglecting the convection motion liquid phase is supported by the findings of [33] who examined the role of natural convection within the pores by discretizing and solving the continuity and momentum equations numerically over the fluid domain. They found that the role of natural convection within the pores turned out to be negligible due to the small values of the pore diameter and temperature difference (the Grashof and Rayleigh numbers based on the pore diameter are of the order of 1 and 10, respectively).…”

Review on heat transfer analysis in thermal energy storage using latent heat storage systems and phase change materials

“…The results indicated that the higher porosity aluminium foam accelerates the attainment of a steady‐state temperature as compared with the foams with lower porosity. Sedeh and Khodadadi reported that highly conductive graphite foam has good potential for improving the thermal conductivity and heat transfer of PCMs. A numerical investigation on the thermal behaviour of sodium nitrate (NaNO 3 ) as a PCM was conducted using the commercial computational fluid dynamics (CFD) software, Fluent .…”
