“Thermal Analysis of Phase Change Materials used in solar Evacuated Glass Tube Collector”

Abstract

Phase Change Materials (PCMs) are widely used in thermal energy storage systems due to their high latent heat capacity. This research paper focuses on the thermal analysis of paraffin wax, a commonly used PCM, when encapsulated in two different containers—plastic and copper bottles. The study aims to compare the thermal conductivity, heat absorption, and dissipation characteristics of both setups under controlled conditions. By monitoring temperature variation over time, the efficiency of each container in enhancing the PCM&  performance is evaluated. Results indicate that the material of the container significantly impacts the rate of heat transfer, with copper demonstrating superior thermal responsiveness. This analysis contributes to the optimization of PCM-based systems in real-world thermal applications.
