STUDI SIFAT TERMOFISIK DAN STABILITAS NANOFLUIDA CuO-MWCNT/AQUADES-ETILEN GLIKOL

---

Nanofluids are fluids containing nano-sized particles and have the ability to improve heat transfer performance compared to conventional fluids. This study examines the thermophysical properties and stability of CuO–MWCNT hybrid nanofluids with a base fluid mixture of distilled water–ethylene glycol. Nanofluids were prepared using a two-step method with variations in volume fractions of 0.2%, 0.4%, and 0.6%, and nanoparticle ratios of 70:30, 50:50, and 30:70. Thermophysical properties testing included viscosity using a Brookfield viscometer at temperatures of 30°C, 60°C, and 85°C, and density using a digital densitometer. The stability of the nanofluids was analyzed visually through sedimentation photos for 30 days. The test data were analyzed using the Taguchi method via Orthogonal Array L9, Signal to Noise Ratio (SNR), and ANOVA to determine the most significant parameter influences. The results showed that increasing temperature decreased the viscosity, while increasing the volume fraction increased the viscosity and density of the nanofluid. The CuO–MWCNT hybrid ratio was shown to affect the thermophysical characteristics and suspension stability. Based on sedimentation observations, nanofluids with low volume fractions showed better stability than those with high concentrations. Overall, the CuO–MWCNT/aquadest–ethylene glycol nanofluid has the potential as an efficient heat transfer fluid and can be optimized by adjusting the nanoparticle concentration, hybrid ratio, and mixing process parameters
