An Experimental Investigation of Heat Transfer of Free Convection on Triangular Fins in Order to Optimize the Arrangement of Fins

摘要

In this study, the effect of free convection heat transfer on a vertical surface on which the triangular fins are vertically placed has been investigated numerically and experimentally. In order to numerically solve the system of governing equations, the finite volume method has been used, and the analysis has been conducted by FLUENT software. Free convection heat transfer in four groups of built fins has been tested using the available testing tool. Results show that increasing the fins increases the coefficient of heat transfer of free convection. In addition, increasing the distance decreases the heat transfer at first until the optimum distance is achieved, and then increasing the distance increases the amount of heat transfer.
