“…Figure 1 Finned tube heat exchanger (Paria et al 2015) Nanofluid, which is a "term used to describe fluids containing dispersed particles of nanoscale, can be formed from nano particles of single element (e.g. Cu, Fe, and Ag), single element oxide (e.g., CuO, Cu2O, Al2O3, and Tio 2,), alloys (e.g., Cu-Zn, Fe-Ni, and Ag-Cu), multielement oxides (e.g., CuZnFe4O4, Ni Fe 2O4, and ZnFe 2O4), metal carbides (e.g., SiC, B4C, and ZrC ), metal nitrides (e.g., SiN, TiN, and AlN),and carbon materials (e.g., graphite, carbon nanotubes, and diamond) suspended in water, ethanol, EG, oil, and refrigerants" (Gupta et al, 2017;Gupta, Tiwari, and Ghosh, 2018;Sundar et al, 2017).…”
