Abstract

Increasing the heat transfer and minimizing the pressure drop value is important in terms of development the thermal performance of heat exchangers, and it is a subject that a large number of studies conducted. To increase the heat transfer rate increase the heat transfer rate, nanofluids with superior thermophysical properties are used in heat exchangers. In this study, the effect of graphite-water nanofluid use on heat transfer, efficiency coefficient and improvement rate in the plate heat exchanger in the combined hot water preparation system was investigated experimentally. In the study, cold water flows were taken as 4, 5, 6, 7 l/min and hot fluid inlet temperatures as 40, 45, 50, 55, 60˚C. According to the results, while the highest improvement rate was achieved at a rate of 0.25% nanofluid by volume, 10% at a volumetric flow rate of 4 l/min, it was determined that the heat transfer increased and the recovery rate decreased as the flow rate increased.

Özet

Isı transferini artırmak ve basınç düşüş değerini en aza indirmek, ısı değiştirgeçlerinin ısıl performansını iyileştirmek açısından önemli olup üzerinde çok sayıda çalışma yapılan bir konudur. Isı transfer oranını artırmak için, üstün termofiziksel özellikli nanoakışkanlar ısı değiştiricilerinde kullanılmaktadırlar. Bu çalışmada birleşik sıcak su hazırlama sisteminde bulunan plakalı ısı değiştiricisinde grafit-su nanoakışkanı kullanımının ısı transferine, etkinlik katsayısına ve iyileştirme oranına etkisi deneysel olarak incelenmiştir. Çalışmada soğuk su debileri 4, 5, 6, 7 l/dk, sıcak akışkan giriş sıcaklıkları ise 40, 45, 50, 55, 60˚C olarak alınmıştır. Elde edilen sonuçlara göre hacimce %0.25 nanoakışkan oranında en yüksek iyileştirme oranı 4 l/dk debi değerinde %10 olarak elde edilirken, debi arttıkça ısı transferinin arttığı ve iyileşme oranının düştüğü belirlenmiştir
