As a first step towards the final goal to control the three-dimensionalizing process of T-S (Tollmien-Schlichting) waves, the property of oblique waves, which appear in the later stage of transition, is studied. It is shown that oblique waves can be generated on a flat-plate boundary layer with inclined roughness element under acoustic forcing., 資料番号: AA0000867019, レポート番号: NAL SP-33}, pages = {83--87}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {斜行T-S波を励起する試み}, volume = {33}, year = {1996} }
