Thermal Conductivity Enhancement of TiO2 Nanofluid in Water and Ethylene Glycol (EG) Mixture

The need to study nanofluid properties has increased over these past centuries in order to provide better understanding on nanofluid thermal properties and behaviour. Due to its ability to improve heat transfer compared to conventional heat transfer fluids, nanofluids as a new coolant fluid have wid...
