TAM VE PARÇALI SİLİNDİRİK KANATÇIK KONFİGÜRASYONLARININ BİR MİNİKANALLI ISI ALICININ TERMOHİDROLİK PERFORMANSI ÜZERİNDEKİ ETKİLERİ

Öz

Bu çalışmada, tam ve parçalı silindirik kanatçık konfigürasyonlarının bir minikanallı ısı alıcının termohidrolik performansına etkileri sayısal olarak incelenmiştir. Bu amaçla, 0.00265 kg/s ile 0.0045 kg/s aralığında dört farklı debi ve üç farklı kanatçık konumu için sayısal çalışmalar ANSYS Fluent yazılımı kullanılarak gerçekleştirilmiştir. Farklı konfigürasyonların hız ve sıcaklık alanlarına, ortalama Nusselt sayısına, Nusselt sayısı oranına, sürtünme katsayısına ve ısı alıcının performans katsayısına olan etkileri değerlendirilmiştir. Çalışma sonucunda, parçalı silindirik kanatçık kullanımının ısı transferi ve basınç düşümü üzerinde önemli etkilerinin olduğu, ısı transferi açısından değerlendirildiğinde MCHS-R2a’nın en iyi sonucu verdiği fakat bu konfigürasyonun akışa karşı olan direnci önemli ölçüde artırdığı belirlenmiştir. Termohidrolik performans açısından değerlendirildiğinde ise MCHS-R2c’nin önemli sonuçlar vadettiği ortaya konmuştur.

EFFECTS OF COMPLETE AND PARTIAL CYLINDRICAL FIN CONFIGURATIONS ON THERMOHYDRAULIC PERFORMANCE OF A MINICHANNEL HEAT SINK

Abstract

In this numerical investigation, the impacts of complete and partial cylindrical fin configurations on the thermohydraulic performance of a minichannel heatsink are studied. ANSYS Fluent software is used to conduct numerical analyses for four distinct mass flow rates ranging from 0.00265 kg/s to 0.0045 kg/s and three distinct fin positions. The effects of various configurations on velocity and temperature fields, average Nusselt number, Nusselt number ratio, friction coefficient, and performance evaluation coefficient are analyzed. According to the study’s findings, using partial cylindrical fins has a substantial impact on both heat transfer and pressure drop. When evaluating heat transfer, MCHS-R2a produces the greatest results, but this configuration greatly raises flow resistance. MCHS-R2c was found to have substantial potential when evaluated in terms of thermohydraulic performance.
