Experimental Investigation of Thermo-Physical Properties of Tri-Hybrid Nanoparticles in Water-Ethylene Glycol Mixture

In recent years, research has focused on enhancing the thermo-physical properties of a single component nanofluid. Therefore, hybrid or composite nanofluids have been developed to improve heat transfer performance. The Al2O3-TiO2-SiO2 nanoparticles suspended in base water (W) and ethylene glycol (EG) at constant volume ratio 60:40 different concentrations were investigated. experiment was conducted for 0.05, 0.1, 0.2, 0.3% temperatures 30, 40, 50, 60, 70 °C. Thermal conductivity dynamic viscosity measurements carried out ranging from 30 °C by using KD2 Pro Properties Analyzer Brookfield LVDV III Ultra Rheometer, respectively. highest thermal tri-hybrid obtained concentration, maximum enhancement increased up 9% higher than fluid (EG/W). Tri-hybrid with concentration 0.05% gave lowest effective 4.8 % temperature. Meanwhile, influenced Furthermore, behaved as Newtonian 0.05 3.0%. (PER) estimated that will aid all samples present. new correlations minimum deviation. As conclusion, combination found optimum condition more advantage other concentrations.
