Experimental Study the Influence of Surface Shape and Roughness of Different Materials on Thermal Contact Conductance in Single and Multilayers Wall

Year 2020, Volume: 4 Issue: 2, 185 - 199, 30.12.2020

Abstract

This paper presents an experimental study, the purpose of which is to know the effect of surface shape on the thermal contact conductance of two solid specimens bonded to each other. The experiment was carried out by placing copper and aluminum specimens in an electric furnace, isolating the surroundings of these specimens and measuring the temperatures at the contact surfaces of the samples. The aluminum specimens used in this study have different surfaces (some specimens have extended surfaces). The experimental results found variations in temperature distribution due to the difference in surface form, by which the aluminum thermal conductivity can be measured at various temperatures ranging from 100oC to 300oC. The results showed the efficiency and effectiveness of extended surfaces and their effect in enhancing heat transfer.

Farklı Malzemelerin Yüzey Şekli ve Pürüzlülüğünün Termal Temas İletkenliğine Etkisi İçin Deneysel Bir Çalışma

Year 2020, Volume: 4 Issue: 2, 185 - 199, 30.12.2020

Abstract

Bu makale, birbirine temas eden iki katı numunenin, yüzey şeklinin ısıl temas iletkenliği üzerindeki etkisini bulmayı amaçlayan deneysel bir çalışmayı sunar. Deney, bakır ve alüminyum numuneleri bir elektrikli fırına yerleştirerek, bu numunelerin çevresini izole ederek ve numunelerin temas yüzeylerindeki sıcaklıkları ölçülerek gerçekleştirilmiştir. Bu çalışmada kullanılan alüminyum numunelerin farklı yüzeyleri vardır (bazı numuneler geniş yüzeylere sahiptir). Deneysel sonuçlar, yüzey formundaki farklılığa bağlı olarak sıcaklık dağılımında farklılıklar buldu; bu sayede alüminyum termal iletkenlik 100°C ila 300°C arasında değişen çeşitli sıcaklıklarda ölçülebilir. Sonuçlar, uzatılmış yüzeylerin verimliliğini ve etkililiğini ve ısı transferini artırmadaki etkilerini gösterdi.
