WebFeb 21, 2024 · There are mainly four types of fins :- 1) Constant Area Straight Fin 2) Variable Area Straight Fin 3) Pin Fin 4) Annular Fin Types of fins in heat transfer The fins are generally used in the following:- 1) Economizer for steam power plant. 2) Convectors for steam and hot water heating system. 3) Radiators of automobiles. WebThis study characterized the contribution to the heat transfer in an array of pin fins that comes from the pin surface itself. Oblong-shaped pins, with a constant height-to-diameter ratio of one, were studied. To gain an understanding of the heat transfer over the pin and correlated flow features through the array, the spanwise, streamwise
