NANOAKIŞKANLARDA KARARLILIĞIN ISI TRANSFERİNİ İYİLEŞTİRME AÇISINDAN ÖNEMİ

Öz

Son yıllarda ısı transferini iyileştirme çalışmalarının nano boyutlardaki parçacıkların etkisi ile oluşturulan nanoakışkanlar üzerinde yoğunlaştığı görülmektedir. Nanoakışkanların ısı transferini artırdığını gösteren birçok çalışma bulunmasına rağmen geleneksel ısı transfer akışkanlarının yerini almasının önünde birçok engel bulunmaktadır. Bunlardan en önemlisi nanoakışkanlarda kararlılık konusudur. Bu konuda yapılan çalışmalar arasındaki çelişkiler, nanoakışkanlara bakış açısının değiştirilmesi gerektiği sonucunu ortaya koymaktadır. Nanoakışkanlar ısı transferini artırmanın yanında yüksek kararlılığa sahip olmalıdır.  Sonuç olarak, nanoakışkanın ısı transferini iyileştirme oranının, kararlılık sağlandıktan sonra ölçülmesinin gerekliliği fikri ortaya çıkmaktadır. Bu araştırmada nanoakışkanlarda kararlılık konusunda yapılan çalışmalar detaylı bir şekilde incelenerek ısı transferi üzerindeki etkileri araştırılmıştır.

THE IMPORTANCE OF NANOFLUIDS STABILITY IN TERNS OF HEAT TRANSFER ENHANCEMENT

Abstract

In recent years, efforts to improve heat transfer seem to have concentrated on the nanofluids created by the effects of nanoparticle powders. There are many studies showing that nanofluids increase heat transfer. There are many obstacles in front of that nanofluids can replace conventional heat transfer fluids. The most important of these is the nanofluids stability concept. Due to the contradictions in the works done in this issue, the outcome of the change of the angle of view to the nanofluids is revealed. In addition to increasing the heat transfer of the nanofluids, the stability must be high. As a result, idea that the heat transfer values of the nanofluids must be measured after stabilization is achieved emerges. In this study, studies on stability in nanofluids were studied and the effects on heat transfer were investigated.
