STUDI SIFAT TERMOFISIK DAN STABILITAS NANOFLUIDA AL2O3 – TiO2 / AQUADES – ETILEN GLIKOL

---

Nanofluids are engineered fluids developed by adding nanoparticles into base fluids to enhance heat transfer capabilities. The use of nanofluids is increasingly important in high-temperature industrial systems such as automotive, power generation, electronic cooling, and transportation, because conventional fluids such as water and ethylene glycol have limited thermal conductivity. This study aims to study the thermophysical properties and stability of Al₂O₃–TiO₂ hybrid nanofluids with a mixture of ethylene glycol aquadest (60:40) as the base fluid. Nanofluids were synthesized using a two-step method with variations in nanoparticle volume fractions of 0.2%, 0.4%, and 0.6%, as well as variations in the ratio of Al₂O₃–TiO₂ nanoparticles. Tests were carried out at temperatures of 30°C, 60°C, and 85°C to analyze viscosity, density, and stability using the photo sedimentation method. Data were analyzed using Taguchi, ANOVA, and Signal-to-Noise Ratio (SNR) methods. The results showed that nanoparticle volume fraction, nanoparticle ratio, and homogenization duration significantly affected viscosity and density, while stirring duration had a relatively small effect. Increasing the volume fraction improved the stability of the nanofluid, with a ratio of 30% Al₂O₃:70% TiO₂ showing the best stability. Overall, the Al₂O₃–TiO₂/ethylene glycol aquadest hybrid nanofluid has potential as a heat transfer fluid with a balance between flow characteristics, stability, and thermal performance, making it worthy of further development in industrial cooling and heat transfer system applications
