New Refrigeration Science Findings from Kyung Hee University Described [Thermal conductivity and heat transfer performance enhancement of phase change materials (PCM) containing carbon additives for heat storage application]

By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Science are presented in a new report. According to news reporting originating from Yongin, South Korea, by NewsRx correspondents, research stated, "In thermal storage system, a high thermal conductivity of Phase Change Materials (PCM) is required to complement the crystallization phenomenon of the PCM during the discharging process. In this study, PCM with carbon additives, Multi-walled Carbon nanotube, Graphite and Graphene, are manufactured and the thermal conductivity of the PCM is measured by the transient hot-wire method for thermal storage application."

Our news editors obtained a quote from the research from Kyung Hee University, "The thermal conductivity of the PCM is enhanced by adding the carbon additives, and the effect of Poly Vinyl Pyrrolidone (PVP) as a dispersion stabilizer on the thermal conductivity is evaluated. It is found that the heat transfer rate enhances up to 3.35 times in the case of Graphite at 5.0 vol%."

According to the news editors, the research concluded: "It is finally concluded that Graphite is the most promising candidate for heat transfer enhancement of stearic acid among three carbon additives even though Graphene gives the highest thermal conductivity enhancement."
