Near-wake flow characteristics of a circular cylinder close to a wall

Flow characteristics in the near wake of a circular cylinder located close to a fully developed turbulent boundary layer are investigated experimentally using particle image velocimetry (PIV). The Reynolds number based on the cylinder diameter ( D) is 1.2×10 4 and the incident boundary layer thickne...

Zusammenfassung:	Flow characteristics in the near wake of a circular cylinder located close to a fully developed turbulent boundary layer are investigated experimentally using particle image velocimetry (PIV). The Reynolds number based on the cylinder diameter ( D) is 1.2×10 4 and the incident boundary layer thickness ( δ) is 0.4 D. Detailed velocity and vorticity fields in the wake region (0< x/ D
