Analysis of entropy generation of different particle size nanofluids at turbulent region in heat exchanger

Saving power or lowering dissipations of heat transfer of fluids is one of the very important proper nowadays. The entropy generation of nanofluids is influenced by many factors such as cross-sectional pipe, physical properties of fluids, heat transfer coefficient, the particle size of nanofluids, and temperature difference. In this research, the issue of SiO2 nanofluid with different concentrations (0.8, 1, 2) wt. % and particle sizes of (25, 35, 50, and 65) nm are studied. The study showed that the entropy generation thermal type is controlled at Re
