Recovery of the wall-shear stress to equilibrium flow conditions after a rough-to-smooth step-change in turbulent boundary layers
Mogeng Li, Charitha M. de Silva, Amirreza Rouhi +4
This paper examines recovery of the wall-shear stress of a turbulent boundary layer that has undergone a sudden transition from a rough to a smooth surface. Early works of Antonia…
Turbulent drag reduction by spanwise wall forcing. Part 2: High-Reynolds-number experiments
Dileep Chandran, Andrea Zampiron, Amirreza Rouhi +5
Here, we present measurements of turbulent drag reduction in boundary layers at high friction Reynolds numbers in the range of . The efficacy of the approac…
Turbulent drag reduction by spanwise wall forcing. Part 1: Large-eddy simulations
Amirreza Rouhi, Matt K. Fu, Dileep Chandran +3
Turbulent drag reduction through streamwise travelling waves of spanwise wall oscillation is investigated over a wide range of Reynolds numbers. Here, in Part 1, wall-resolved larg…
Near wall coherence in wall-bounded flows and implications for flow control
Milad Samie, Woutijn Baars, Amirreza Rouhi +4
Opposition-control of the energetic cycle of near wall streaks in wall-bounded turbulence, using numerical approaches, has shown promise for drag reduction. For practical implement…
