HEAT TRANSFER ANALYSIS OF FINS BY FINITE ELEMENT METHOD (FEM): A REVIEW

Abstract

The Engine cylinder is one of the primary engine elements, that is subjected to excessive temperature differences and thermal stresses. Fins are placed on the surface of the cylinder to enlarge the amount of heat rejection by convection. The present study described the reviews on heat dissipation improvement and the equivalent pressure decreases over a plane surface, pin fins different shaped (circular, rectangular) fitted with tube-shaped cross-sectional so as to optimize the improvement in the heat transfer rate. The heat resistance is considered as the multiple thermal performance features. The conclusions of geometric limitations, fin length, fin area and material of fin with base temperature to ambient temperature variation on the heat transfer performance of fin arrays and the optimum fin separation value has been optimized. The effect of fin density on the heat transfer behavior is examined Heat transfer also increases with the thermal conductivity of the material and with the pin fin length.
