摘要：
This paper gives an outline of solar collector exergy analysis. The effects of several nanofluids (NFs) and a redesigned absorber tube on the collector's exergy efficiency were discussed. It also includes a comparison of solar collector exergy efficiency with different Reynolds numbers (Re), mass flow rates, and inlet temperatures. Exergy analysis is a more accurate representation of a system's performance. The study found that using NFs and inserts at the same time considerably improves the exergy efficiency of collectors. In addition, using NFs instead of base fluids improves the system's exergy efficiency. © 2022
