摘要：Finned surface has been extensively used for convective heat transfer of internal combustion engines and several electronic kits etc. Here cylindrical and square fin of copper and aluminum materials were preferred for analysis. Thermocouples were attached all over the surface of the fin in equal distances. The experiments were conducted to analyze the parameters such as heat transfer rate through fin, fin efficiency and effectiveness through free and forced co nvection heat transfer mode. The fins were coated with Nano graphene for all of the above cases and changes in heat transfer through the fin, fin efficiency and effectiveness were studied. It is found that there is a considerable increase in heat transfer an d other parameters on Nano coating
