Near-wall streaks are almost completely suppressed by the boundary-layer suction. Immediately downstream of the suction strip, residual turbulent fluctuations convecting from upstream can generate low-speed streaks. Subsequently the streaks break down due to their instability, leading to retransition to wall turbulence. The low-frequency fluctuations associated with the near-wall streaks are found to grow algebraically up to 10 percent of the free-stream velocity in term of r.m.s. value of u-fluctuation. The spacing of near-wall streaks appearing in the retransition process is not so different from that of developed wall turbulence without suction., 資料番号: AA0045947013, レポート番号: NAL SP-56}, pages = {45--48}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {乱流変動を伴う境界層における壁近傍ストリーク構造の発生と成長}, volume = {56}, year = {2002} }
