State-of-the-art review of nanofluids in solar collectors: A review based on the type of the dispersed nanoparticles

Qingang Xiong et al.

Summary: Nanofluids, as a new generation of fluids, have shown to be more suitable for heat transfer applications compared to conventional fluids, with the type of nanoparticles dispersed being a key parameter. This review focuses on the different types of particles used in nanofluid research, particularly in solar collectors, exploring their impact on heat transfer and the classification of nanoparticles. Studies suggest that Al2O3-based nanofluids are widely considered in solar collectors, with non-metallic based nanofluids potentially more efficient for enhancement. Negative aspects such as thermo-physical instability and reduced efficiency at high nanoparticle volume fraction are also highlighted, along with suggestions for future research directions.
