Özet
The heat transfer coefficient is a common engineering concept and a significant number of researchers are focusing on improving the heat transfer performance of the system by increasing the heat transfer coefficient. Heat transfer enhancement techniques are broadly classified in three broad categories: passive, active and compound techniques. This study is concerned with the effect of fins placed inside a rectangular channel on heat transfer and pressure drop to be concave and convex against flow. The effect of some independent parameters such as Reynolds number, height, diameter, number and angle of the fins on Nusselt number, friction coefficient were experimentally studied. Turbulent flow experiments were performed for the range 2514-13111 of Reynolds number. The results showed that Reynolds number is the most effective parameter. Based on the Reynolds number, the heat transfer increased between 1.4-2.8 times, friction coefficient increased between 1.1-3.4 times according to smooth channel. © Avestia Publishing, 2017.
