Abstract |
Thermal storage materials considering phase-changing materials (PCM) have attracted many researchers for thermal management of energy crises due to better temperature range to suit the thermal storage applications. However, the effectiveness of PCMs is affected by very low thermal conductivity and this deficiency limits the use of PCMs as an efficient thermal storage material. To increase the thermal conductivity of PCM, different nanoparticles (NPs) with a higher value of thermal conductivity are added which are called nano PCM. This paper presents the preparation and characterization of phase change material enhanced by metallic NPs alumina (Al2O3) and nonmetallic NPs multiwall carbon nanotubes (MWCNTs). The aim of this study is to create the nano PCM by adding Al2O3 & MWCNTs NPs in Paraffin wax at 2 wt%,4 wt% and 6 wt%. The results showed that in the case of pure paraffin wax, the maximum peak temperature obtained after 90 min is 61.53 °C. In the case of alumina oxide maximum peak t
