Abstract
Nanofluid is a new class of fluids engineered by dispersing nanometer-size solid particles into base fluids such as water, ethylene glycol, engine oil, cutting fluids, etc. Researches have shown that the thermal conductivity and the convection heat transfer coefficient of the fluid can be largely enhanced by the suspended nanoparticles. Recently, tribology research shows that lubricating oils with nanoparticle additives (MoS2, CuO, TiO2, Diamond, etc.) exhibit improved load-carrying capacity, antiwear and friction reduction properties. These features make the nanofluid very attractive in some cooling and/or lubricating application in many industries including manufacturing, transportation, energy, and electronics, etc. In this study, the effect of CuO nanofluid in minimum quantity lubrication machining was investigated

Abstract
Nanoakışkanlar, su ve benzeri etilen glikol, makine yağı, kesme yağı vb. temel akışkanlara nano boyutta ilave edilen katı parçacıkların yeni bir mühendislik tasarımıdır. Yapılan araştırmalar nanoparçacıklar kullanılarak akışkanın ısı iletkenliği ve ısı transfer katsayısının büyük ölçüde geliştirilebileceğini göstermektedir. Son zamanlarda, tribolojik araştırmalar nanoparçacık katkılı (MoS2, CuO, TiO2, Diamond, vb) yağlama yağlarının daha fazla yük taşıma kapasitesi, anti-aşınma ve sürtünmeyi önemli ölçüde azaltan özellikleri gösterdiğini ortaya koymaktadır. Bu özellikler, imalat, ulaştırma, enerji, ve elektronik gibi birçok sanayi bazlı soğutma ve veya yağlama uygulamasında nanoakışkanları çok cazip hale getirmektedir. Bu çalışmada CuO nanoakışkanın metal işlemede kullanılmasının etkileri üzerinde durulmuştur.
