Experimental Study for Heat Transfer Enhancement under Turbulent Flow Conditions by Increasing the Surface Area of Engine Cylinder Fins

Abstract

Enhancement of fin efficiency of engine cylinder fins in air cooled engines under forced convection and turbulent flow was investigated by three different types of proposed fins and one conventional fin the material of all the fin is aluminium. The experiments were carried out by increasing the surface area of all proposed fins(13.86%,13.05%,32.59% respectively) compared to conventional fin.All the fins are placed on the heater which acts as a heat source and keeping air flow rate constant. The results showed that the fin efficiency for the proposed fin-3 increased by 12.39% compared to conventional fin.
