Abstract

Nano boyutta metal oksit parçacıklar içeren nanoakışkanlar ve hibrit nanoakışkanların ısıl sistemlerde çalışma akışkanı olarak kullanıldıklarında geleneksel akışkanlara göre ısıl iletkenlik bakımından daha üstün performans sergiledikleri bilinmektedir. Çalışma akışkanlarının ısıl ve fiziksel özellikleri birçok ısı ve akış problemlerinin çözümünde önemli parametreler olarak yer alır. Bu çalışmada CuO, ZnO, MgO parçacıkları ve CuO+ZnO, MgO+CuO, MgO+ZnO hibrit parçacıklarının nano boyutta olacak şekilde saf su içerisine belirli oranlarda katılarak elde edilen nanoakışkanların termofiziksel özellikleri teorik olarak literatürdeki modeller kullanılarak belirlenmiştir. %0.5, %1, %2,%2.5 olacak şekilde farklı konsantrasyona sahip nanoakışkanların ısıl iletkenlik, özgül ısı, vizkozite değerleri hesaplanmış ve modeller karşılaştırılmıştır.
