Manyetik Nanoakışkanın Termosifon Tipi Isı Borusunun Performansına Etkisi

Bu çalışmada termosifon tipi ısı borusunda çalışma akışkanı olarak manyetik nanoakışkan kullanılarak performansın değişimi incelenmiştir. Baz akışkan su içerisine ağırlıkça %2 oranında manyetik nanopartikül olan Demir(III) Oksit (Fe3O4) ve %0,2 oranında yüzey aktifleştirici (TRITON X-100) eklenerek nanoakışkan elde edilmiştir. Elde edilen nanoakışkanın içerisinde nanopartiküllerin asılı kalmasını sağlamak amacıyla ultrasonik banyoda yaklaşık 4 saat karıştırılmıştır. Deneylerde kullanılan termosifon tipi ısı borusu 1m uzunluğunda ve 15mm dış çapa sahiptir. Deneyler kondenser bölgesinde kullanılan soğutma suyunun farklı debilerinde, evaporatör bölgesinde de farklı güçlerde yapılmıştır.

Effect of Magnetic Nanofluid on Performance of Thermosiphon Type Heat Pipe

In this study, the variation of the performance was investigated by using magnetic nanofluid as the working fluid in the thermosiphon type heat pipe. Nanofluid was obtained by adding 2% by weight of magnetic nanoparticle Iron(III) Oxide (Fe3O4) and 0.2% surfactant (TRITON X-100) into the base fluid water. In order to keep the nanoparticles suspended in the obtained nanofluid, it was mixed in an ultrasonic bath for about 4 hours. The thermosiphon type heat pipe used in the experiments has a length of 1m and an outer diameter of 15mm. The experiments were carried out at different flow rates of the cooling water used in the condenser region and at different powers in the evaporator region.
