Volumetric visualization of coherent structure in a low Reynolds number turbulent boundary layer

Monage 6: x-y resampled data at z / = 1.59, z⁺ = 475

Flow is from left to right (x-direction) in the images, each of which measures: L_x / = 3.85, L_y / = 1.49 (in viscous units: L_x⁺ = 1150, L_y⁺ = 444). Time begins in the upper right hand corner, proceeds downwards, then continues in the next column to the left. Note that structures appear to be connected in the horizontal direction; horizontally adjacent images are separated in time by 10 t which translates via the Taylor hypothesis to: U_e 10 t ~ 3.4 ~ L_x /
