Abstract

The characteristics of three-dimensional intense uv-structures (Qs) in a strongly decelerated large-velocity-defect boundary layer are analyzed. The Q2 and Q4 structures are found to be different from those of turbulent channel flows studied by Lozano-Durán et al. (J Fluid Mech 694:100-130, 2012). They are less streamwise elongated, less present near the wall and wall-detached structures are more numerous. Moreover, contrary to channel flows, wall-detached Q2, and Q4 structures contribute significantly to the Reynolds shear stress.
