An experiment was performed to investigate heat transfer around the second rectangular cylinder of three cylinders arranged in a line on a laminar boundary layer. The length of the cylinder was 30 mm, and the height was varied at 3, 5 and 10 mm and their pitch varied from 40 to 60 mm. The main results obtained were as follows: the heat transfer coefficient around the cylinder increased drastically as increasing in the free stream velocity. The local heat transfer coefficients decreased in the order of the front, upper and rear face. For laminar flow type, the dependency of the Reynolds number on the heat transfer was Nu ∝ Re^<0.5>, while for turbulent flow type, it was different in each face. There existed a correlation between the maximum turbulent intensity on the cylinder and the heat transfer coefficient.
