Summary

HEAT TRANSFER FROM A FIN INVOLVES TWO MECHANISMS, NAMELY CONDUCTION WITHIN THE FIN AND CONVECTION FROM THE FIN SURFACE TO THE SURROUNDING FLUID. A NUMERICAL SOLUTION OF THE COUPLED FIN CONDUCTION EQUATION AND THE LAMINAR, FORCED CONVECTIVE BOUNDARY LAYER EQUATIONS FOR A CYLINDRICAL FIN HAS BEEN CARRIED OUT. THE EFFECTS OF PRANDTL NUMBER AND THE CONDUCTION CONVECTION PARAMETER ON THE HEAT TRANSFER CHARACTERISTICS HAVE BEEN STUDIED. WHILE THE SIMPLE MODEL PREDICTS THE FIN EFFECTIVENESS AND THE OVERALL HEAT TRANSFER RATE FROM THE FIN WITH TOLERABLE ACCURACY OVER THE ENTIRE RANGE OF PRANDTL VALUES, ITS PREDICTIONS OF LOCAL HEAT FLUX AND FIN TEMPERATURE ARE IN SUB-STANTIAL ERROR.
