Thermophysical Properties of Alumina-Ethanol-Water Based Nanofluids
Addition of nanosized particles as an additive to the fluid in order to improve the properties of fluid has gained much attention in recent era. Limited studies are reported in literature for the preparation and estimation of thermophysical properties of nanofluids based on binary mixture of liquids. Thermophysical properties of nanofluids including effective density and effective viscosity of alumina nanoparticles based nanofluids are measured at a temperature range of 20-60°C. The study is carried out in binary mixture of ethanol and water at different concentrations. Alumina nanoparticles of 50 nm are used at different particle loading i.e. 0-0.3 wt% in different proportions of ethanol and water. The analysis of measured experimental values indicates that the addition of nanoparticles in different concentrations has significant effect on the effective density and the effective viscosity of fluids. The predicted values are estimated from correlation coefficients as a function of temperature.
