Experimental investigation on melting/freezing characteristics of nanocomposite PCMs

Abstract

This study describes the results of an experimental investigation into the solidification and melting characteristics of a recently developed Nano Composite PCM composed of oleic acid, myristic acid, and GO nanoparticles. In this study, the findings of the investigation are discussed. This report presents the results and conclusions of the investigation that was conducted (NPs). Independent distributions of graphene oxide nanoparticles (GO NPs) with mass fractions of 0.1, 0.2, and 0.3 wt% were produced in the base PCM (oleic acid and myristic acid) to determine which offered the best thermal conductivity enhancement. This was done to discover which offered the greatest thermal conductivity improvement. Therefore, this technique was used to determine how much of an improvement in heat conductivity could be accomplished. This was conducted to determine how much of an increase was possible. After the GO NPs were created, the researchers utilised FESEM to analyse both the size and morphology of the GO NPs in order to gain a more in-depth understanding of the GO NPs. Using a laser flash analyser, it was discovered that the composite PCMs had a higher thermal conductivity than they had previously (LFA). According to the findings of this study, the time required to complete the melting and solidification processes for composite PCMs is significantly less than that required for base PCM. Due to the fact that each composite PCM has its own unique composition, this is the case. As a result, the newly synthesised PCM has the potential to be viewed as a viable alternative for the capture of solar energy for use in low-temperature heating operations. This is because this alternative has the potential to be considered a viable option for solar energy gathering.
