열전달 향상을 위한 확장표면 또는 핀

Extended surface or fin for an enhancement of heat transfer

Abstract

The concept for heat transfer from the extended surfaces is explained.  Many shapes of fin profile are presented.  Some of the representative solutions for the fin problem are introduced.  Comparison of a two-dimensional analytical method for a rectangular plate and that for a triangular fin is made.  For this comparison, separation of variables method, incremental search method, Newton-Raphson method, Newton's second-order method and forced analytic method are commented briefly.
