| Popis: | We address the issue of the generation mechanism of near-wall reverse flow (NWRF) events in a fully developed turbulent duct flow using direct numerical simulations and particle image velocimetry at a relatively low Reynolds number (Cardesa et al., J. Fluid Mech., vol. 880, 2019) indicates the generality of the proposed mechanism. |
