Effect array shape on the performance of fin

Mechanical Engineering

Force convection from vertical surfaces with large surface element is encountered in several technological applications of particular interest of heat dissipation in several forms. Force convection represents an inherently reliable cooling process. The purpose of this project is to find out the best of different fin patterns by calculating the heat transfer rate. The considered fin pattern types are Parallel horizontal fin pattern, Parallel split pattern and V-fin array pattern. Project consists of self-made experimental setup having Nichrome wire is used for heating. It is supplied with the stabilized A.C. supply. The electrical heat input was controlled through Dimmer stat and measured with wattmeter. Different observation like temperature, heat input etc. is taken by performing experiment and these will be used to calculate heat transfer rate for every single fin pattern mentioned above. Result of this experiment is going to be used to determine the fin pattern with highest heat transfer rate, i.e. which fin will provide greater cooling effect. As not the all pattern with different fin height and pitch distance can be practically used for the experiment, so that analysis of these fins is also included as for the future aspects, in which fin dimension can be varied and further more pattern can be designed for more results..
