Experimental Investigation of the Thermophysical Properties of TiO2/Propylene Glycol–Water Nanofluids for Heat-Transfer Applications

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

Nanofluids have been prepared by dispersing TiO2 nanoparticles in 70:30% (by weight) water–propylene glycol mixture. The thermal conductivity and viscosity were found experimentally at various temperatures with the volume concentrations 0.1–0.8%. The results indicate that the thermal conductivity of the nanofluids increases with the volume concentration and temperature. Similarly, the viscosity of the nanofluids increases with the volume concentration but decreases with increase in the temperature. Correlations have been proposed for estimating the thermal conductivity and viscosity of the nanofluids. The potential heat transfer benefits of their use in laminar and turbulent flow conditions has been explained.
