An asymmetric concave parabolic fin is analyzed using a two-dimensional analytical method. In this analysis, for equal value of the ratio of heat loss from the bottom surface to that from the fin, the relationship between the fin length and the fin base height is presented. Fin effectiveness and fin efficiency are presented as a function of the fin base height and the convection characteristic number. For equal value of fin effectiveness, the relationship between the fin length and the convection characteristic number as well as the relationship between the fin base height and the fin length are presented. One of the results shows that the fin effectiveness decreases very slightly as the convection characteristic number increases, whereas the fin efficiency decreases linearly as the convection characteristic number increases.
