چکیده
This study develops a novel composite phase change material (PCM) based onparaffin/hydrophobic expanded perlite and exfoliated graphene nanoplatelets as heat transferpromoter. The experimental analysis was systematically carried out on fabrication,characterization and testing the thermal storage properties of composite PCM. The micro-morphology characteristics of composite PCM showed that the xGnP forms aninterconnecting network with the porous EP, indicating the improvement in the heat transferperformance of composite PCM. Contact angle measurements showed that the compositePCM can prevent the PCM leakage in the TES system due to the hydrophobic surfaceproperties of supporting material. Furthermore, thermal conductivity measurements revealedthat the composite PCM with 1 wt% of xGnP boosts the thermal conductivity by up to 49%compared to the ordinary composite PCM.

متن کاملGeneralized energy failure criterion
Discovering a generalized criterion that can predict the mechanical failure of various different structural materials is one of ultimate goals for scientists in both material and mechanics communities. Since the first study on the failure criterion of materials by Galileo, about three centuries have passed. Now we eventually find the "generalized energy criterion", as presented here, which appe...
