Effects of TiO₂ nanoparticles on thermal conductivity of heat transfer oil

Abstract

There is a lack of thermophysical data of heat transfer oil and nano-oil in the high temperature range of 50–300°C for designing and developing heat transfer oil furnace and its heating systems. In the present study, the thermal conductivity values of heat transfer oil and TiO₂ nano-oil in the above high temperature range were measured by a newly developed high-temperature thermal conductivity meter. Based on the principle of least square method, the thermal conductivity values obtained from experiments were fitted separately, and the correlation between thermal conductivity and temperature of heat transfer oil and TiO₂ nano-oil was obtained. The results show that the thermal conductivity and the increased percentage of thermal conductivity of TiO₂ nano-oil are proportional to the increase of particle size and mass fraction of nanoparticles, but thermal conductivity is in reverse proportion to the increase of temperature and the increased percentage of thermal conductivity is less affected by temperature.
