In this study, for two different most commonly used fittings (L, T) in industrial systems, effect of the nanofluid usage on the pressure drop and pressure loss coefficient were numerically analysed. Taking the water as base fluid, the nanofluid is obtained by adding different concentrations of aluminium, copper and titanium-based nanoparticles. In order to examine the effect of the concentration on pressure loss and flow structure, different nanofluids which are at different concentrations were studied ((A2O3, 0.3%, 0.5%, 1%, 2%, 3%) and CuO (1%, 2%, 4%). The thermophysical properties of nanofluids were taken from previous studies. The results have been verified with the results to be given in the literature. Two different turbulent models were used for numerical analysis, the standard k- ε and the standard k- ω turbulence model, which are widely preferred. The result of the computations for each nanofluid showed that as the concentration increases, the local losses increase with the increase of viscosity. It has been determined that the most suitable model is the standard k-ε for both fittings.

Yapılan bu çalışmada endüstriyel sistemlerde en çok kullanılan 2 farklı tesisat bağlantı parçasının (L, T) içerisinden nanoakışkan geçirilip, bu bağlantı parçalarının basınç düşüşleri ve basınç kayıp katsayıları sayısal olarak incelenmiştir. Nanoakışkan, temel akışkan su alınarak içerisine farklı konsantrasyonlarda alüminyum, bakır ve titanyum esaslı nanoparçacıkların eklenmesiyle elde edilmiştir. Artan konsantrasyonun basınç kaybı ve akış yapısı üzerinde etkisini incelemek için farklı konsantrasyonlarda farklı nanoakışkanlar incelenmiştir ((A2O3, %0,3, %0.5,
%1, %2, %3) ve CuO (%1, %2, %4). Nanoakışkanların termofiziksel özellikleri daha önce yapılmış olan çalışmalardan alınmıştır. Hesaplama sonuçları, literatürdeki sonuçlar ile doğrulanmıştır. Sayısal çözümlemelerde yaygın olarak tercih edilen standart k- ε ve standart k- ω türbülans modeli olmak üzere 2 farklı model kullanılmıştır. Elde edilen hesaplar sonucunda incelenen her akışkanda, konsantrasyon arttıkça viskozitenin artışı ile yerel kayıpların da arttığı ortaya konulmuştur. En uygun modelin her iki bağlantı parçası için de standart k-ε olduğu belirlenmiştir.
