Abstract
Thermophotovoltaic technology has significantly improved the utilization rate of solar energy by effectively addressing the issues of high temperature and low electrical efficiency in photovoltaic cells. In this study, a photovoltaic-thermal (PV-T) system model was simulated using water and alumina nanofluid with three different volume fractions ranging from 0.1% to 3%. The effects of operational parameters such as inlet temperature, solar radiation, ambient temperature, and mass flow rate of the cooling fluid were numerically investigated. The simulation was conducted using ANSYS Fluent software with a two-phase mixture model. The risers were considered as longitudinal circular tubes, and simulations were performed for mass flow rates ranging from 10 L/h to 60 L/h for both water and alumina nanofluid with three different volume fractions. The thermal conductivity and thermal expansion coefficient of the nanofluid were introduced into the software via a User-Defined Function (UDF). The variations in fluid outlet temperature, solar cell temperature, pressure drop, thermal efficiency, electrical efficiency, and overall efficiency were analyzed as a function of mass flow rate. The results indicate that the nanofluid with a 2.5% volume fraction achieves the highest thermal efficiency.
