The present effort documents the population trends of prograde and retrograde
spanwise vortex cores in wall turbulence outside the buffer layer. Large ensembles
of instantaneous velocity fields are acquired by particle-image ...
The spatial signatures of retrograde spanwise vortices in wall turbulence are assessed
from particle-image velocimetry measurements in the streamwise–wall-normal plane
of a zero-pressure-gradient turbulent boundary layer ...
