• Relaminarization properties of the turbulent boundary layer by a sink-flow were experimentally investigated. Lateral and transverse correlation hot-wire probes and a X-shaped probe were used. In the coherent structure analysis with u-level method, large amplitude sweep and ejection decreased with the relaminarization within the sink-flow section. This result shows that the downflow of a high-speed fluid and the upflow of a low-speed fluid were prevented by the relaminarization. On the other hand, the width and height of coherent vortex increased with the relaminarization within the sink-flow section. This variation of the coherent vortex affected an extent and an intensity of the coherent structure.
