Heat transfer of cylinders in the forced convection problem has been an issue for the design of efficient and high performance heat exchangers. In this paper, heat transfer characteristics of two identical cylinders with various cross section shapes are investigated using a commercial software, CFD-ACE+. A cylinder with a circular cross section shape is selected as a base model. The cylinders with elliptical and square cross sections are also selected in order to compare the heat transfer performance between various types of cylinders. In the present paper, the heat transfer characteristics of those cylinders will be discussed focusing on the interference effects and flow characteristics.
