Abstrakt

To control the flow around a square prism, a rod was set up in upstream of the prism. The length of side of the prism was 20 mm and the diameter of the rod changed from 1 to 6 mm. The spacing between the axes of the prism and the rod was 40 to 80 nun, and the Reynolds number ranged from 5.3 × 103 to 3.2 × 104 The average heat transfer increases by 40 % compared with that of the square prism only. Further, the reduction of the drag coefficient becomes to about 70 %.
