内容記述 | Appearance and growth of near-wall low-speed streaks are examined in the transition process of boundary layer relaminarized by suction through a short strip of perforated wall. 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. | |||||
