Experimental investigations on the fluid flow and heat transfer around two circular cylinders arranged in tandem were carried out. The Reynolds number was varied in the range 3.9×10^3≦Re≦6.24×10^4, and the distance between the cylinders was L/d=1.3. Three flow patterns were found at the above distance and range of Reynolds. The effect of the Reynolds number on the local heat transfer coefficients was made clear in connection with the flow characteristics. The limiting Reynolds numbers between two patterns were 1.95×10^4 and 2.92×10^4. Drastic change in the heat-transfer coefficients due to the flow patterns appeared at the rear stagnation point of the upstream cylinder and at the front and rear stagnation points of the downstream cylinder.
