Reynolds number effects in the outer layer of the turbulent flow in a channel with rough walls

Turbulent channel flow measurements for two different rough surfaces have been compared with a smooth reference case. A range of Reynolds numbers, Re τ ∊ ⟨ 360,6000 ⟩ , has been investigated using hot-wire anemometry. Reynolds stresses and third-order moments are shown to be very little affected by...
