Statistical analysis of the impact of F(e)O(3) and Z(n)O nanoparticles on the physicochemical and dielectric performance of monoester-based nanofluids

This article deals with a comparative study of the physicochemical and electrical properties of monoesters of castor oil compared with their counterparts based on FeO(3) and Z(n)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 F(e)O(3) NFs and 7.6%, 9.91% and 12.7% for Z(n)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 Z(n)O samples. For the same concentrations, the fire point shows an increment of 4%, 3% and 2% for F(e)O(3) samples and a regression of 8.75%, 6.88% and 5.63% for Z(n)O samples. As for the breakdown voltage, for the same concentrations we observe respectively an increment of 43%, 27%, 34% for the F(e)O(3). 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%.
