An experimental study on thermal conductivity of T2 copper with different surface roughness

Abstract

Recent previous studies have shown that there is a correlation between heat conductivity and surface materials. In this project, the heat conductivity 3 different samples of T2 copper with different surface roughness was studied. This was done by measuring the temperature of the samples at 9 different point using SOLTEQ Heat Conduction Study Bench (Model HE106). The surface roughness of the different samples was achieved using sandpaper and measured using the (SURFTEST SJ-410) where the different surface roughness was A: Ra=0.379μm, B: Ra=0.71μm, C: Ra=0.053μm. The sample was heated using a heater with 10W of power. From the collected data, it was observed that the specimen with the smoothest surface roughness has the best performing heat transfer with the specimen C that have the highest decreasing percentage temperature followed by specimen B and specimen A.
