The present study is focused on the use of a phase-change material (PCM) for heat storage applications. Beeswax is investigated in this work as a PCM for heat storage because of its high latent heat. Utilizing beeswax has drawbacks because of elevated melting point and limited heat conductivity. In the present investigation, CuO nanoparticles (1–5 wt%) were added and tested based on analysis of thermal conductivity, latent heat, heat capacity characteristics and viscosity analysis. CuO nanoparticles found to give the improved result for thermal conductivity enhancement, increment in latent heat for both melting and solidifying stage. While inclusion of CuO nano particles, the specimens’ heat capacity increases by 2–2.2%, with improvement in thermal conductivity upto 2.31 W/m.K. There is also in increment in viscosity.

摘要

The present study is focused on the use of a phase-change material (PCM) for heat storage applications. Beeswax is investigated in this work as a PCM for heat storage because of its high latent heat. Utilizing beeswax has drawbacks because of elevated melting point and limited heat conductivity. In the present investigation, CuO nanoparticles (1–5 wt%) were added and tested based on analysis of thermal conductivity, latent heat, heat capacity characteristics and viscosity analysis. CuO nanoparticles found to give the improved result for thermal conductivity enhancement, increment in latent heat for both melting and solidifying stage. While inclusion of CuO nano particles, the specimens’ heat capacity increases by 2–2.2%, with improvement in thermal conductivity upto 2.31 W/m.K. There is also in increment in viscosity.
