Spatial correlation
of the longitudinal velocity fluctuations in a plane normal to the wall. A prefered
direction at an angle of 20° to the wall downstream is clearly visible.
R21
Spatial cross correlation of the longitudinal and
transverse velocity components. The upstream angle at 45 ° corresponds to ejections.
Instantaneous velocity and
vorticity in a plane normal to the wall. Coherent structures are clearly visible.
