| چکیده مقاله |
| Growing environmental concerns—including global warming, rising CO₂ emissions, the greenhouse effect, and increasing energy demand—have accelerated the adoption of renewable energy sources. Among the primary options, solar, wind, and geothermal energy stand out, with solar energy being the most abundant and environmentally friendly. Solar energy can be harnessed either as heat or converted directly into electricity through photovoltaic (PV) panels. However, prior studies have demonstrated that PV panel performance declines as panel temperature rises under high solar radiation. This study aims to enhance PV panel efficiency by implementing cooling techniques using water, Ag-water nanofluid, and TiO₂ nanofluid. The cooling system’s performance was evaluated numerically through computational fluid dynamics (CFD) simulations in Ansys Fluent. A mathematical model was employed to calculate the thermophysical properties of the nanofluids required for the simulations. CFD results indicate that the average surface temperature and outlet temperature of the cooling fluid show minimal differences between nanofluids and water. Nevertheless, increasing the cooling fluid flow rate reduces panel temperature, thereby improving electrical efficiency. The cooling system proves most effective under high solar intensity. At 1000 W/m² solar intensity and a flow rate of 3.5 L/min, the Ag-water nanofluid achieved the highest improvement, yielding a 44.66% increase in PV cell efficiency, corresponding to an electrical efficiency of 19.7%. |
