Abstract
Rectangular aluminium fins were preferred for analysis and coated by carbon nano tubes using PVD to enhance the heat transfer rate of fins Convective heat transfer rates for coated and noncoated surfaces were calculated and compared The temperature and heat transfer characteristics were investigated using Nusselt Grashof Prandtl and Rayleigh numbers and also optimized by Taguchi method and ANOVA analysis The average percentage of increase in fin efficiency is 5Â
