The purpose of this study is to show distributions of the pressure coefficient and the heat transfer coefficient on a cylinder which is laid in a wake of another cylinder and to clarify the influence of the clearance between the two cylinders on the flow and heat transfer characteristics around the cylinder. The experiment was mainly made at the Reynolds number of 5×10^4. The naphthalene sublimation technique was employed to obtain the heat transfer coefficient distribution of the whole surface of a cylinder. Distributions of the pressure coefficient and the heat (mass) transfer coefficient changed complicatedly according to the clearance and the axial position, and those changes were caused by the axial flow along the cylinder made by the non-uniformity of the oncoming flow in addition to the turbulence intensity of it.
