Fin on a Pipe (Insulated Tip): Minimum Conditions for Fin to Be Beneficial
Comparisons are made of the one-dimensional and two-dimensional centerline temperature profiles and heat lost ratios for a radial fin of uniform thickness on a pipe. Effects of the Biot number, fin thickness, and size ratio (ratio of radial distances of the tip and root) are investigated. In particular, the more restrictive two-dimensional results as to the usefulness of the fin are demonstrated. Further, the distortion of the two-dimension temperature profile for intermediate values of the Biot number exhibit regions where waste of material in this shape of fin occurs. Finally, information is presented that relates the fin size (radially) and the Biot number magnitude for which the fin is beneficial.
