Experimental investigation of solar collector efficiency enhancement using surfactant stabilized MWCNT and Al₂O₃ hybrid nanofluid
, the 0.5 vol% hybrid nanofluid delivered a thermal efficiency of 83.9%. Exergy efficiency reached 3.0% at 1065 W/m² for 0.5 vol% hybrid nanofluid which is more than double that of water. These results demonstrate the synergistic advantage of hybrid nanofluids under real operating conditions, establishing their potential as high-performance working fluids for advanced solar thermal collectors.
