This study analyzes and optimizes a design for a rectangular profile annular fin using two-dimensional analytical method. Temperature distribution along the fin height in addition to fin length is presented to show the two-dimensional effect. The heat transfer, fin length, and fin height are optimized as a function of the ratio of convection characteristic numbers, fin volume, and the overall wall resistance. Corresponding to the optimum condition, the fin effectiveness is shown as a function of the ratio of convection characteristic numbers, fin volume and convection characteristic number over the fin surface for the case when the overall wall resistance is negligibly small.
