Study of Analysis, Design and Performance of Fin
Abstract: This paper discusses the use of extended surface heat transfer in heat exchangers. The size and cost of an exchanger is dependent upon the heat duty, the allowable pressure drop, and the geometry of the heat transfer area. The dominance of this resistance is often broken by the use of extended surfaces (fins), which will result in a lower area and hence smaller exchanger. This paper will consider which, if …
