Bu çalışmada, türbülanslı, tam gelişmiş iç akışta farklı boyutsuz geometrik
ölçülere sahip kanatçıklı yapılardan gerçekleşen kararlı rejimdeki ısı
transferini belirlemeye yönelik deneysel bir çalışma yürütülmüştür. Geometrik
parametrelerin ısı taşınım katsayısı ve Nusselt sayısına etkisi araştırılmıştır.
Deneysel veriler işlenerek Reynolds sayısı aralığı, ve boyutsuz geometrik
ölçülerin (kanatçıklar arası mesafe/kanatçık kalınlığı),
(kanatçık üstü kanal yüksekliği/kanatçık boyu)
iken ampirik Nusselt sayısı eşilişkisi
elde edilmiştir.
In this work, experimental study searching the
heat transfer over finned surfaces with different non-dimensional geometric
parameters in fully developed turbulent internal flow has been performed. The
effect of geometric parameters on local convective heat transfer coefficient
and Nusselt number was analyzed. For the Reynolds number, and (distance between fins/fin thickness), (height of channel above fin tip/fin height) empirical
Nusselt number correlation has been obtained.

30.03.2021-Beginning with our April 2021 (26/1) issue, in accordance with the new criteria of TR-Dizin, the Declaration of Conflict of Interest and the Declaration of Author Contribution forms fulfilled and signed by all authors are required as well as the Copyright form during the initial submission of the manuscript. Furthermore two new sections, i.e. ‘Conflict of Interest’ and ‘Author Contribution’, should be added to the manuscript. Links of those forms that should be submitted with the initial manuscript can be found in our 'Author Guidelines' and 'Submission Procedure' pages. The manuscript template is also updated. For articles reviewed and accepted for publication in our 2021 and ongoing issues and for articles currently under review process, those forms should also be fulfilled, signed and uploaded to the system by authors.
