Extended surfaces are widely used for the cooling of heat generating devices either internally or externally in natural convection process. In the current work tree shaped fin is preferred for analysis. CFD analysis (ANSYS 15) is done on the tree fin placed in an enclosure using FLUENT and heat input in the form of temperature is given to the base of the fin. The heat transfer characteristics were calculated for various temperature inputs. In order to increase the performance of the system, heat transfer rate is to be enhanced. Considering this, the orientation of the fin is varied simultaneously for each temperature input. The heat transfer characteristics have acquired better results for temperature input 363K and orientation 900. Taguchi and ANOVA analysis are performed and concluded that the temperature is having more influence on the system performance.
