The experimental study of the surface tension of titanium dioxide-ethylene glycol nanofluids

The paper summarizes the experimental study on the physical properties such as surface tension and density of ethylene glycol based nanofluids containing titanium dioxide nanoparticles different in terms of phase: anatase phase, rutile phase and their mixture. The samples prepared using two-step method were in various mass fractions: 0.01, 0.02, 0.03, 0.04 and 0.05, without using any surfactants. During the experimental study the surface tension and mass density were measured in temperature range from 283.15 to 318.15 K. The findings exposed the effect of TiO2 nanoparticles concentration as well as nanoparticles phase on these properties. The addition of nanoparticles to the ethylene glycol causes the increase in the value of the surface tension and density. Finally, the outcomes were compared to theoretical correlation proposed by Pak and Cho.
