EXPERIMENTAL STUDY OF SINGLE-PHASE FLUID FLOW AND HEAT TRANSFER CHARACTERISTICS IN RECTANGULAR MICROCHANNELS

Öz:

In this study, single-phase laminar flow of deionized water through microchannel heat sinks is investigated experimentally. Heat sinks including twenty-nine parallel rectangular channels have been used as the test samples. Three different channel geometries with different aspect ratio (AR = 1.22, 0.82 and 0.37) but with the same hydraulic diameter (100 µm) are considered. A constant heating power of 9 W is applied to the test section. The range of Reynolds number varies from 12.3 to 47.3. It is disclosed that increasing AR increases Nusselt number while decreasing the friction factor.

DİKDÖRTGENSEL MİKROKANALLARDA TEK FAZLI AKIŞKAN AKIŞI VE ISI TRANSFERİ KARAKTERİSTİKLERİNİN DENEYSEL İNCELENMESİ

Öz:

Bu çalışmada, deiyonize suyun mikrokanallı ısı alıcılardaki tek fazlı laminer akışı deneysel olarak incelenmiştir. Yirmi dokuz paralel dikdörtgensel kanallı ısı alıcılar test numuneleri olarak kullanılmıştır. Aynı hidrolik çapa (100 µm) fakat farklı boyut oranlarına sahip (AR = 1.22, 0.82 and 0.37) üç farklı kanal geometrisi dikkate alınmıştır. Test bölgesine, 9 W olacak şekilde sabit bir ısıtma gücü uygulanmıştır. Reynolds sayısı 12.3 ile 47.3 arasında değişmektedir. Artan AR değerlerinin Nusselt sayısını artırdığı ve sürtünme faktörünü azalttığı görülmüştür.
