Abstract

When the studies on nanofluids in recent years are examined, it is seen that hybrid nanofluids are used to improve their thermophysical properties. The most important step in the comparison of hybrid nanofluids with single nanofluids and basic fluids (water, oil, ethylene glycol, etc.) is to determine their thermophysical properties. The aim of this study is to determine the thermal conductivity and viscosity values of Al2O3-MWCNT/Pure Water nanofluids with increasing volumetric ratio and temperature, finally compare the obtained values with the existing correlations. In the study, Al2O3–MWCNT/Pure Water hybrid nanofluids with 0.1%, 0.2% and 0.3% volumetric ratios were prepared by suspending Al2O3 and MWCNT nanoparticles in pure water at mixing ratios of 0:100%, 50:50% and 100:0%. Experimental results showed that both the thermal conductivity and viscosity of the prepared hybrid nanofluids increased with the nanoparticle volume concentration. It was determined that the thermal conductivity value of the hybrid nanofluid prepared at a 50:50 mixture ratio of 0.1% by volume was higher than the mono nanofluids. Compared to pure water, the highest thermal conductivity increase of 8.56% was obtained for 0.3% (0:100) Al2O3-MWCNT/Pure Water nanofluid at 50°C. The viscosity values increased with the increase of the volumetric ratio and the highest increase was determined as 54.73% for the 0.3% (50-50) Al2O3-MWCNT/Pure Water hybrid nanofluid at 20°C compared to pure water. The maximum viscosity decrease that occurs when the temperature rises from 20°C to 50°C is 55.72% for the 0.3% (50-50) Al2O3-MWCNT/Pure Water hybrid nanofluid at 50°C.

Abstract

Nanoakışkanlar ile ilgili son yıllarda yapılan çalışmalar incelendiğinde termofiziksel özelliklerinin iyileştirilmesi için hibrit nanoakışkanların kullanıldığı görülmektedir. Hibrit nanoakışkanların tekli nanoakışkanlar ve temel akışkanlar (su, yağ, etilen glikol vb.) ile kıyaslanabilmesi için en önemli adım termofiziksel özelliklerinin belirlenmesidir. Bu çalışmanın amacı Al2O3-MWCNT/Saf Su nanoakışkanlarının ısıl iletkenlik, viskozite değerlerini artan hacimsel oran ve sıcaklık ile belirlemek, sonuç olarak da elde edilen değerleri mevcut korelasyonlar ile karşılaştırmaktır. Çalışmada Al2O3 ve MWCNT nanopartikülleri %0:100, %50:50 ve %100:0 karışım oranlarında saf su içinde süspanse edilerek %0.1, %0.2 ve %0.3 hacimsel oranına sahip Al2O3–MWCNT/Saf Su hibrit nanoakışkanları hazırlanmıştır. Deneysel sonuçlar, hazırlanan hibrit nanoakışkanların hem ısıl iletkenliğinin hem de viskozitesinin nanopartikül hacim konsantrasyonu ile arttığını göstermiştir. %0.1 hacimsel oranda %50:50 karışım oranında hazırlanan hibrit nanoakışkanının ısıl iletkenlik değerinin mono nanoakışkanlardan daha yüksek olduğu belirlenmiştir. Saf su ile kıyaslandığında en fazla ısıl iletkenlik artışı %8.56 olarak 50°C’de %0.3 (0:100) Al2O3-MWCNT/Saf Su nanoakışkanı için elde edilmiştir. Hacimsel oranın artışı ile viskozite değerleri artmış ve saf suya kıyasla en fazla artış 20°C’de %0.3 (50:50) Al2O3-MWCNT/Saf Su hibrit nanoakışkanı için %54.73 olarak belirlenmiştir. Sıcaklığın 20°C’ den 50°C’ ye çıkmasıyla meydana gelen en fazla viskozite azalışı 50°de %0.3 (50:50) Al2O3-MWCNT/Saf Su hibrit nanoakışkanı için %55.72’dir.
