Non-equilibrium three-dimensional boundary layers at moderate Reynolds numbers

Abstract: Non-equilibrium wall turbulence with mean-flow three-dimensionality is ubiquitous in geophysical and engineering flows. Under these conditions, turbulence may experience a counter-intuitive depletion of the turbulent stresses, which has important implications for modelling and control. Yet, current turbulence theories have been established mainly for statistically two-dimensional equilibrium flows and are unable to predict the reduction in the Reynolds stress magnitude. In the present work, we propose a multis… Show more

“…The primary Reynolds shear stress () also decreases with increasing , as observed in the recent DNS work by Lozano-Durán et al . (2020) in a turbulent channel flow with a sudden spanwise pressure gradient. Not only the inactive motion ( and ) but also the active motion ( and ) are changed in a 3DTBL.…”
