Abstract

Sanayinin birçok alanında, değişik türde ve çeşitte soğutucu akışkanların kullanılıyor olmasının yanı sıra, literatüre de birbirinden farklı özelliklere sahip birçok yeni akışkan eklenmiştir. Her soğutucu akışkan için literatürde bulunan mevcut yoğuşma ısı transfer korelasyonlarıyla ısı transfer katsayısı hesabı yapmak, birçok hatayı beraberinde getirmektedir. Bu makalede birçok soğutucu akışkana yer verilmiş ve literatürde bulunan en popüler korelasyonlardan 9 korelasyon ile deneysel veriler karşılaştırılmıştır. Akışkan türleri, kütle akış hızları, sıcaklıkları ve boru çapları gibi parametreler değiştirilerek ısı transfer sonuçları Java Crimson Editör ile hesaplanmıştır. Isı transfer katsayı sonuçları grafiksel analiz metotları ile karşılaştırmalı olarak irdelenmiştir.
