Thermodynamic Optimization of Hybrid Nanofluid Flow in Parabolic trough Solar Collectors for Solar-Powered Agricultural Machinery

C. B. Ogunlade, A. M. Obalalu & E. O. Fatunmbi · Physical Science International Journal · 2026

The efficiency of solar-powered farm machinery is often limited by inadequate heat transfer in conventional working fluids, reducing the thermal performance of parabolic trough solar collectors (PTSCs). Enhancing the thermophysical properties of the working fluid using a binary h...
