| Summary: | In modern agriculture, enhancing irrigation efficiency is crucial for achieving sustainable crop production and meeting the growing global food demand. One promising solution is the use of advanced technologies, such as hybrid nanofluids, to optimize the performance of solar water pumps equipped with parabolic trough collectors. This study explores the application of an aluminum-titanium hybrid nanofluid (Oldroyd-B hybrid nanofluid, O-BHNF) within a solar water pump system, aiming to significantly boost irrigation efficiency while reducing water wastage. The hybrid nanofluid is created by dispersing aluminum alloy and titanium alloy nanoparticles in Society of Automotive Engineers (SAE) 50 engine oil, a process that enhances the thermal conductivity of the fluid and improves heat transfer capabilities. The research presents a comprehensive theoretical model that includes various factors such as viscous dissipation, solar radiation, and electromagnetic heat transfer, which are crucial in accurately predicting the system's performance. This model was developed to study the complex dynamics of momentum, energy, and entropy generation within the system. To solve the equations governing these factors, the Shifted Legendre Collocation Scheme (SLCS) was employed, offering precise and reliable numerical solutions. The findings reveal that increasing the solid volume fraction of aluminum and titanium nanoparticles in the nanofluid significantly improves its thermal distribution profile. Compared to conventional nanofluids, the hybrid nanofluid demonstrated a 2.7% increase in thermal efficiency, with the minimum recorded enhancement being 2.1%. These results suggest that aluminum-titanium hybrid nanofluids are highly effective in enhancing heat transfer, thus improving the overall performance of solar-powered irrigation systems. By optimizing the thermal efficiency of solar water pumps, this study contributes to the advancement of more efficient and sustainable agricultural practices, highlighting the potential of hybrid nanofluids to play a pivotal role in addressing water scarcity and energy conservation in agriculture. |
