Experimental study on the viscosity of hybrid nanofluid and development of a new correlation

Abstract

The present experimental analysis targeted on the preparation of water based (Al2O3-SiC-TiO2) ternary hybrid nanofluids by the mistreatment of two-stage methodology. Each vol. fraction sample of ternary hybrid nanofluids consists of an equal proportion of Al2O3-SiC-TiO2 nanoparticles for this analysis. The result for the dynamic viscosity of ternary hybrid nanofluids was examined for a temperature range of 35–40 °C and within a vol. fraction range of (0.01–0.1%). Analysis extended to the morphology characterization study through SEM image, together with an EDX analysis for 0.1% vol. fraction ternary hybrid nanofluid. Furthermore, based on the supported results, a new correlation was projected for the dynamic viscosity of ternary hybrid nanofluid, and also compared with the relevant literatures. The results revealed that the rise in vol. fraction, contains a larger role in increasing the interior resistance of fluid and the low vol. fractions have a weaker result on the viscosity of ternary hybrid nanofluids. The best relative consistency was discovered within 0.1% vol. fraction and, consistent with the obtained results, the margin of deviation within the intervals of ±2.6%.
