Effects of Working Temperature on Thermo-Physical Properties and Forced Convection Heat Transfer of TiO2 Nanofluids in Water–Ethylene Glycol Mixture

Nanofluids as a new coolant have overcome the limitations in thermal performance faced by conventional fluids such as water, ethylene glycol (EG) and oil based fluids. The objective of the study is to investigate the properties and heat transfer performance of TiO2 nanofluids in water-EG mixture at...
