Abstract

In this experimental study, air side heat transfer and flow characteristics of L-footed spiral fin-and-tube heat exchanger have beenanalyzed. There were four rows of tubes in the air flow direction and four tubes per row in the heat exchanger. The hot water was flowedthrough the tubes while the ambient air was flowed cross flow over the tubes. The results were presented as plots of friction factor fand Colburn j factor against Reynolds number. The air-side heat transfer coefficient and pressure drop were also presented againstfrontal air velocity. Additionally, The correlations for j and f factors were also obtained from the experimental data.

Özet

Bu deneysel çalışmada, L-ayaklı spiral kanatlı boru tipi bir ısı değiştiricinin hava tarafındaki ısı transferi ve akış özellikleri analiz incelenmiştir. Isı değiştiricide hava akışı yönünde dört sıra boru ve her sıradada dört adet boru vardır. Çevre hava borular üzerinden çapraz olarak geçerilirken, sıcak su ise boruların içerisinden geçirilmiştir. Sonuçlar, Reynolds sayısına karşı sürtünme faktörü f ve Colburn j faktörünün grafikleri olarak sunulmuştur. Hava tarafındaki ısı taşınım katsayısı ve basınç düşüşünün de hava hızına karşı değişimi gösterilmiştir. Bunlara ek olarak, j ve f faktörlerinin korelasyonları da deneysel verilerden elde edilmiştir.
