Improvement of Stability and Thermal Conductivities of Oil-Based Nanofluids in Optimum Acid-Base Admixture Values

Abstract

In this work, it has been aimed to improve the stability and thermal conductivity of the nanofluids that use the heat transfer oil, which is frequently used in the industry, as the base fluid. For this purpose, the nanofluids were synthesized by using Al2O3 (alumina) and TiO2 (titanium dioxide) nanoparticles in the mass ratios of 1%, 2% and 3% and the heat transfer oil as the base fluid. H2SO4 (sulphuric acid) or KOH (potassium hydroxide) at 5 N (normality) valence solutions were added separately to the prepared nanofluids at the determined volumetric ratios (10-3%, 3.5×10-3%, 5.3×10-3% and 8×10-3%). By being prepared nanofluids separately with acid and base, the highest enhancement rates in the stability appeared were about 24% for 2% Al2O3 by mass and 3.5x10-3% H2SO4 by volume mixture in the alumina-acid case and about 50% for 1% Al2O3 by mass and 5.3x10-3% KOH by volume mixture in the alumina-base case. Similarly, the highest enhancement rates in the stability of the nanofluids were about 75% for 3% TiO2 by mass and 10-3% H2SO4 by volume mixture in the titanium dioxide-acid case and about 77% for 2% TiO2 by mass and 10-3% KOH by volume mixture in the titanium dioxide-base case.

Yağ Bazlı Nanoakışkanların Optimum Asit-Baz Katılım Değerlerinde Kararlılık ve Isıl İletkenliklerinin İyileştirilmesi

Abstract

Bu çalışmada, endüstride sıklıkla kullanılan ısı transfer yağını baz akışkan olarak kullanan nanoakışkanların kararlılığının ve ısıl iletkenliğinin arttırılması amaçlanmıştır. Bu amaçla, %1, %2 ve %3 kütle oranlarında Al2O3 (alümina) ve TiO2 (titanyum dioksit) nanopartikülleri ve baz akışkan olarak ısı transfer yağı kullanılarak nanoakışkanlar sentezlenmiştir. Hazırlanan nanoakışkanlara belirlenen hacimsel oranlarda (%10-3, %3,5×10-3, %5,3×10-3 ve %8×10-3) H2SO4 (sülfürik asit) veya KOH (potasyum hidroksit) 5 N (normalite) değerlikli çözeltileri ayrı ayrı eklenmiştir. Nanoakışkanlar asit ve baz ile ayrı ayrı hazırlanarak, ortaya çıkan stabilitedeki en yüksek artış oranları, alümina-asit durumunda kütlece %2 Al2O3 ve hacimce %3,5x10-3 H2SO4 karışımı için yaklaşık %24 ve alümina-baz durumunda kütlece % 1 Al2O3 ve hacimce %5.3x10-3 KOH karışımı için yaklaşık %50 olmuştur. Benzer şekilde, nanoakışkanların stabilitesindeki en yüksek artış oranları, titanyum dioksit-asit durumunda kütlece %3 TiO2 ve hacimce %10-3 H2SO4 karışımı için yaklaşık %75 ve kütlece %2 TiO2 ve 10-3 için yaklaşık %77 olmuştur.
