Abstract

Sağlamış oldukları birçok fayda nedeniyle ısıl sistemlerde geleneksel iş akışkanları yerine nanoakışkan çözeltilerinin kullanımı son yılların en popüler konularından biri olmuştur. Bu deneysel çalışmada alüminyum nitrür (AlN) nanoparçacıkları içeren sulu nanoakışkan çözeltisi hazırlanmış ve farklı çalışma koşulları altında çalışan düz bir ısı borusunda test edilmiştir. Deneylerde kullanılan dairesel kesitli ısı borusu et kalınlığı 1 mm, iç çapı 13 mm ve uzunluğu 1000 mm olacak şekilde bakır malzemeden imal edilmiştir. Nanoparçacıkların sağlamış olduğu etkileri gözlemleyebilmek amacıyla deneyler önce saf su ardından nanoakışkan çözeltisi için gerçekleştirilmiştir. Yapılan deneylerde ısı boruları için performans göstergesi olan ısı borusunun ısıl direnci ve verimi karşılaştırmalı olarak ele alınmış, ısı borusu duvar sıcaklığındaki değişimler incelenmiştir. Deneyler sonucunda elde edilen veriler saf su yerine nanoakışkan kullanımıyla ısı borusu verimimin iyileştirilebileceğini ortaya koymuştur. Saf su yerine alüminyum nitrür nanoparçacıkları içeren nanoakışkanın iş akışkanı olarak kullanımıyla ısıl direnç ve verimdeki en yüksek artışlar sırasıyla %10,9 ve %45,6 olmuştur.

Experimental Investigation of the Influences of AlN/Deionized Water Nanofluid on Heat Pipe Performance Parameters

Year 2020, Volume: 8 Issue: 4, 858 - 871, 29.12.2020

Abstract

Utilization of nanofluidic solutions instead of conventional working fluids in thermal systems has become one of the most popular topics in recent years due to the many benefits they provide. In this experimental study, an aqueous nanofluid solution containing aluminum nitride (AlN) nanoparticles was prepared and tested in a plain heat pipe under different operating conditions. The circular heat pipe used in the experiments was made of copper material with a wall thickness of 1 mm, an inner diameter of 13 mm and a length of 1000 mm. In order to observe the effects of nanoparticles, experiments were initially carried out for deionized water and then for nanofluid solution. In the experiments, the thermal resistance and efficiency of the heat pipe, both of which are the performance indicators for heat pipes, were comparatively studied, and the alterations in temperature of the heat pipe wall were monitored. The data obtained from the experiments revealed that the heat pipe efficiency can be improved by employing nanofluid instead of deionized water. With the use of nanofluid containing aluminum nitride nanoparticles instead of deionized water as the working fluid, the maximum enhancements in thermal resistance and efficiency were recorded as 10.9% and 45.6%, respectively.
