000014566 520__ $$2eng$$aNonlinear optimal coherent structures have been computed in the turbulent channel flow at Reτ = 180. A scale separation has been obtained suitably choosing the optimization time scale characterising the inner and the outer region dynamics. The optimization provides wavy streaky structures in the inner region and hairpin vortices in the outer one at the target time. The time evolution of the hairpin optimal vortices has been analysed to understand its role in sustaining turbulence.
