The initial development of turbulence wedge is characterized with a rapid growth of the disturbed region in the spanwise direction. The so-called inflectional instability is responsible for the broke-out of the disturbance at off-center positions in the wake of the roughness element., 資料番号: AA0000867014, レポート番号: NAL SP-33}, pages = {61--62}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {乱流楔の初期発達について}, volume = {33}, year = {1996} }
