Abstract
The objective of this study is to investigate the thermophysical properties of copper (Cu) based fluids; thermal conductivity and dynamic viscosity of the water, ethylene glycol (EG) and a mixture of water and ethylene glycol (water/EG) suspended with Cu particles. Furthermore, in this study, an engine coolant test rig was built to investigate the heat transfer performance of Cu-based fluids as a new engine coolant. Initially, the Cu-based fluids were produced by using two-step method and their thermophysical properties were investigated experimentally based on the Cu particles concentration, temperatures, types of surfactant and particles sizes. The stability of the Cu-based fluids was observed for 12 days. It showed that the thermal conductivity of Cu-based fluids increased with particles concentration and temperatures. In addition, the temperature variations are more significant factor to enhance the Cu-based fluids thermal conductivity than particles sizes. The dynamic viscosity of Cu-based fluids with 0.1 – 0.5 vol.% particles concentration were comparable to the conventional engine coolants such as pure water and water/EG. The surfactants in this study; Polyvinylpyrrolidone (PVP) and entyltrimenthylammoniumbromide (CTAB) had stabilized the Cu-based fluids up to 14 days based on the particles concentration and the types of base fluids. The Cu-based fluids showed better heat transfer capabilities compared to the conventional engine coolants and it could be considered as advanced engine coolant with further researches on specific areas.
