Namely, objective is to verify Tani's hypothesis that distributed fine rough surface can even reduce turbulent drag in a certain range of Reynolds number. To verify above hypothesis, the net drag of a flat plate wrapped by a sheet with micron-sized distributed surface geometries was measured directly. At the range of higher Reynolds number, a limited amount of drag reduction was observed in the case of certain kinds of rough surface geometries. The present result requires a new explanation how turbulent energy is suppressed in the turbulent boundary layer. On the other hand, at the range of lower Reynolds number, 7-9 percent drag reduction was observed in the surface covered with micron-sized hair. By measuring velocity distributions, it was found out that these drag reduction is owing to transition delay.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
