EXPERIMENTAL ANALYSIS OF HEAT TRANSFER FROM RECTANGULAR FIN ARRAY AT DIFFERENT INCLINATIONS BY NATURAL CONVECTION

Heat transfer enhancement is the major research area in which many researchers are working to fulfill the need heat exchangers having high heat transfer abilities. This work consists of the study of heat transfer enhancement rectangular fin array at different inclinations. In this work angle of inclination of the fin array has been maintained at 0⁰, 30⁰, 45⁰, 60⁰ and 90⁰. This work is conducted for the experimental analysis of heat transfer from Rectangular fin array at different inclinations by natural convection. In this work fin arrays with different angles of inclinations are tested and their results are studied to find out their effect on the heat transfer from fin array. The results of this study shows that with change in angle of inclinations the heat transfer coefficient and the Nusselt number also changes. At 0⁰ inclinations both the heat transfer coefficient and the Nusselt number has lowest magnitudes in entire study. At 45⁰ inclinations both the heat transfer coefficient and the Nusselt number has highest values.
