摘要：Heat transfer by convection between a surface and the fluid surrounding can be increased by attaching tothe surface called fins. The heat conducting through solids, walls, or boundaries has to be continuously dissipated to thesurroundings or environment to maintain the system in a steady state condition. In many engineering applications largequantities of heat needed to be dissipated from small areas. The fins increase the effective area of a surface therebyincreasing the heat transfer by convection. Rectangular fin and triangular fins are straight fins numerically and usingcomsolsoftware. Triangular fins are attractive, since for an equal heat transfer it requires much less volume thanrectangular fin. Hence the fins have practical importance because it gives maximum heat flow per unit mass with easeof manufacture. In an air-cooled engine, rectangular and triangular fins are provided on the periphery of engine cylinder.Heat transfer analysis is carried out by placing rectangular and then triangular fins. Analysis is carried out by varyingtemperatures on the surface of the cylinder from 200 ºC to 600ºC and varying length from 6 cm to 14 cm. Inputparameters such as density, heat transfer coefficient, thermal conductivity and thickness of fin are taken and outputparameters such as rate of heat flow, heat flow per unit mass, efficiency and effectiveness are determined. Comparisonsare presented with rectangular fins.
