Abstract:The thermal characteristics of a single fin with all possible types of heat transfer is analyzed. The heat transfer coefficient is assumed to vary following a power-law type formula. The temperature distribution, tip temperature, and fin efficiency are given in implicit forms and solved by iterative procedures. The results are plotted against fin parameter for various exponents. No solution is found when the fin parameter exceeds a specific value, and which is believed to be related to thermal instability.
