Apin fin with variable fin base thickness is optimized usinga two-dimensional analytic method. The values of the inner walltemperature and fin volume are given as constants. The finbase temperature varies with variation in the fin base thickness,fin outer radius, fin length, and convection characteristic number. Underthese conditions, the optimum heat loss, the corresponding optimum fineffectiveness, fin length, and fin outer radius are presented asfunctions of the fin base thickness, fin volume, and convectioncharacteristic number. One of the results shows that both theoptimum heat loss and optimum fin length decrease linearly withincrease in the fin base thickness.
