Thermal properties of nanoliquids prepared on the basis of natural ester modified by nanoparticles TiO₂ and C₆₀

In this paper the results of the researches concerning thermal properties of insulting nanoliquids received on the basis of natural ester, titan dioxide TiO₂ and fullerene C₆₀ were presented. Thermal conductivity, viscosity, density and specific heat are these thermal properties. The range of the temperature was changing from 25°C to 80°C. These properties are crucial from the viewpoint of heat transfer coefficient by insulating liquid used in insulating system of power equipment; thus, they influence on temperature distribution inside the equipment. The possibility of receiving steady nanoliquids was also analyzed. The impact of natural ester modification by nanoparticles and surfactant on thermal properties of received nanoliquids was proved.
