Abstract
We revisit clustering of coherent Reynolds shear stress producing eddies in wall bounded turbulent flows. We question the plausibility of the strict alignment of the packets of vortices that supposedly lead to very-large-scale motions. Attention is later drawn to the self-exciting Hawkes stochastic processes to model and understand the organization of coherent vortices into clusters, and their spatial organization in the logarithmic layer.
