Abstract

A previous paper by the authors introduced a new set of parameters for describing the heat transfer properties of fins, namely, the thermal transmission matrices or ratios. They were devised to facilitate the analysis of a conglomerate of such fins in an array of extended surface. The present paper elaborates on the status and validity of the new parameters, discussing their superiority over the classic notion of fin efficiency with regard to adaptability and versatility. Tabulations of the new parameters for spines and radial fins are also included.
