Resumo
This work deals with the experimental investigation on thermophysical properties of TiO2-nanofluids and characterization of morphology and structure of this metal oxide nanoparticle. Non-aqueous liquids like silicone oil and ethylene glycol are used as base fluids to prepare the nanofluids. Thermophysical properties including viscosity and thermal conductivity of these nanofluids are measured at different concentrations and temperatures. Results showed that silicone oil-based TiO2 nanofluid is Newtonian and the viscosity of this nanofluid increases with the loading of nanoparticles but it decreases nonlinearly with increasing temperature. Existing viscosity models are found unable to predict the viscosity of nanofluids. Although the effective thermal conductivity of both the silicone oil and ethylene glycol-based nanofluids increased with the TiO2 concentration, the enhancement of their thermal conductivity was found to decrease with increasing temperature.
