Thermally Asymmetric Annular Rectangular Fin Optimization
The optimum design of a single annular rectangular fin under thermally asymmetric conditions using a two-dimensional analysis was presented. The influence of different parameters, such as the fin volume, the ratio of the fin-bottom convection characteristic number to the top convection characteristic number, and the ratio of the fin-tip convection characteristic number to top convection characteristic number, to the optimum design were also discussed. It was observed that the optimum heat loss, fin length, and the fin height increase as the fin volume increases when other variables are fixed. It was shown that the optimum fin design is not obtainable when some parameters are beyond certain values.
