Isı Transferi Akışkanı Olarak Eriyik Tuz Kullanılan Bir Gövde Boru Tipi Isı Değiştiricisinin Hesaplamalı Akışkanlar Dinamiği Programı ile Analizi

Bu çalışmada eriyik tuz kullanılan bir gövde borulu ısı değiştiricisinin ısı transfer performansı bir hesaplamalı akışkanlar dinamiği (HAD) programıyla analiz edilmiştir. Bu çalışma literatürde yapılan bir deneyi doğrulamak için gerçekleştirilmiştir. Ticari bir HAD programı olan ANSYS Fluent 14.5 sürümü bu çalışmada kullanılmıştır. Eriyik tuz ısı değiştiricisine farklı sıcaklık aralıklarında (360 ˚C – 400 ˚C) ve farklı debilerde (0,48 – 1,87 m3/h) girmektedir. Elde edilen sayısal sonuçlar ile literatürden seçilen çalışmadaki deneysel sonuçlarla karşılaştırılmıştır ve iyi bir uyum sağlandığı görülmüştür. Bu çalışmada geliştirilen sayısal HAD modeli ileriki çalışmalarda kullanılabilecektir.

Analysis with Computational Fluid Dynamics Software of a Shell-and-Tube Heat Exchanger Using Molten Salt as Heat Transfer Fluid

In this present study, heat transfer performance of a shell and tube heat exchanger used molten salt is analyzed by a computational fluid dynamic (CFD) programing. The model is prepared regard as a literature study that includes experimental results for validation. ANSYS 14.5 numerical package software is used in the solution of cases. The special heat transfer fluid, molten salt is used as fluid material that has been used between 360 ˚C – 400 ˚C and 0,48 – 1,87 m3/h. The numerical results are compared with experimental results in literature and a good conformity has been achieved with considering limited numerical errors. In this study may be used in future studies developed numerical CFD models.
