A circular cylinder and an airfoil with different types of surface roughness as well as those with single or double rows of holes were tested. In particular a cylinder with double rows of holes placed across its diameter shows a drag reduction for fairly wide range of attack angle. It amounts to as much as 38 percent in comparison to a smooth surfaced cylinder in the Reynolds number range of 5,000-9,000., 資料番号: AA0000109011, レポート番号: NAL SP-28}, pages = {45--49}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {孔列のある2次元物体を過ぎる流れと抵抗}, volume = {28}, year = {1995} }
