ABSTRACT

The main contents of this project and thesis include the design, construction, determination of fin efficiency, fin effectiveness and heat transfer by using different combination of fins, in practical field of mechanical and electrical engineering there are large number of engines and machines which work on the basis of heat energy transfer and requires cooling of the body. In many applications where water cooling or other means of cooling system may not be applied fin cooling may be the on of the options. Fins are extended surfaces of heat generating body that increase the rate of heat transfer and reject heat from the body to keep it cool for providing its operations efficiently. In this project work rectangular, triangular and inverse parabolic fin were considered. Heat transfer can be studied either by maintaining constant heat flux or constant temperature. This work was carried out at constant temperature to the base plate. This thesis compares the theoretical and experimental values of quality of heat transfer for all shape and position of the fins. It has been observed that the theoretical values are higher than their respective experimental values. The project work was carried out by placing the fin at vertical position.
