Statistical analysis of the impact of Fe O3 and Zn O nanoparticles on the physicochemical and dielectric performance of monoester-based nanofluids

Abstract

This article deals with a comparative study of the physicochemical and electrical properties of monoesters of castor oil compared with their counterparts based on FeO3 and Zn O nanoparticles. The results are also compared with those in the literature on triesters, and also with the recommendations of the IEEE C 57.14 standard. The data is analysed statistically using a goodness-of-fit test. The analysis of the viscosity data at 40 °C shows an increase in viscosity. For concentrations of 0.10 wt%, 0.15 wt% and 0.20 wt% these are respectively 5.4%, 9.69%, 12.9% for Fe O3 NFs and 7.6%, 9.91% and 12.7% for Zn O NFs. For the same concentrations, the increase in acid number is respectively 3.2%, 2.9%, 2.5% for FeO3 samples and 3.18%, 2.0%, 1.2% for Zn O samples. For the same concentrations, the fire point shows an increment of 4%, 3% and 2% for Fe O3 samples and a regression of 8.75%, 6.88% and 5.63% for Zn O samples. As for the breakdown voltage, for the same concentrations we observe respectively an increment of 43%, 27%, 34% for the Fe O3. The results show an improvement on partial discharge inception voltage with FeO3 of 24%, 8.13% and 15.21% respectively for the concentrations 0.10 wt%, 0.15 wt% and 0.20 wt%.
