概要

• 論文の詳細を見る

• In this report, results of an experimental investigation which was performed to eliminate the streamwise vortices arising in the nominally two-dimensional turbulent boundary layer, using the procedures which made the main stream uniform completely by replacing bad screens with appropriate ones and cutting those off, are presented. The results are compared with the previous authors' values and the effects of the open area ratio of the screen are confirmed. The differences between the flow fields in which the streamwise vortices exist and the completely two-dimensional flow fields are discussed and the feature of velocity defect region is clarified.
