Exploring the Optical and Electrical Characteristics of MgO/SiC-H2O Nanofluids for Thermal Energy Storage

Abstract

Heat is transferred to storage medium during the charging phase of thermal energy storage (TES), and it is then released during the discharging phase. It may be used to industrial operations like metallurgical transformations or solar power facilities. Heat is stored in materials that alter temperature, phase, or chemical composition in sensible, latent, and thermochemical media, respectively. Optimal heat storage has a long history. This study describes investigating the optical and electrical properties of MgO/SiC-H2O nanofluids for applications including thermal energy storage. Results indicate that when MgO/SiC NP concentrations were raised to 1.2 gm/L, absorbance rose by approximately 66.9% and transmittance by about 54%. Additionally, the increase in MgO/SiC NP concentration will raise absorbance, which indicates improved nanofluid dispersion. Additionally, when MgO/SiC nanoparticle concentrations approach 1.2 gm/L, the electrical conductivity of nanofluids increases by roughly 49.2%, and the melting time reduces as the concentration of MgO/SiC nanoparticles rises.
