First the development of subharmonic streak instability is examined by using artificially-generated spanwise-periodic low-speed streaks in a laminar boundary layer. Up to the nonlinear saturation stage of the streak instability, the disturbance development along each low-speed streak is similar to that observed in a single low-speed streak. Beyond the saturation stage, the neighboring quasi-streamwise vortices developing along each low-speed streak interact with each other, causing an arch-like vortex structure to develop away from the wall. After the breakdown of the primary low-speed streaks, near-wall streaks newly develop downstream. The developed low-speed streaks have lateral spacing of 100 wall units, the same as the value in wall turbulence. Secondly two-dimensional suction is applied to a turbulent boundary layer through a perforated wall strip to realize a quasi-laminar boundary layer with suction-survived high-intensity turbulence, and spanwise-periodic low-speed streaks are artificially introduced there. The results show that under such high-intensity background turbulence the streak breakdown is governed not by the linear instability process but by the transient disturbance growth.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
