This study presents the experimental results on the density, surface tension, and optical properties of ethylene glycol-based nanofluids containing silicon dioxide. Surface tension values, density, refractive index, and extinction of the nanofluids were determined in a specific temperature range and presented in the paper.
In this paper, the results of the experimental study on density, surface tension and optical properties of ethylene glycol-based nanofluids containing silicon dioxide have been presented. The nanofluid-air surface tension values were determined in the temperature range from 283.15 K to 318.15 K with Du Nouy ring method with the commercial equipment and self-made station. To determine the surface tension of a fluid, the information about its density is required; therefore, density of all examined nanofluids was measured in the same temperature range, and results were summarized in the paper. The refractive index of SiO2-EG nanofluids was determined in the same temperature range in which the surface tension was examined. Finally, the extinction (UV-Vis spectra) of these materials was examined and presented.
