Experimental study of a turbulent boundary layer with a rough-to-smooth change in surface conditions at high Reynolds numbers
Mogeng Li, Charitha M. de Silva, Daniel Chung +3
This study presents an experimental dataset documenting the evolution of a turbulent boundary layer downstream of a rough-to-smooth surface transition. To investigate the effect of…
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…
Pressure drag reduction via imposition of spanwise wall oscillations on a rough wall
Rahul Deshpande, Aman G. Kidanemariam, Ivan Marusic
The present study tests the efficacy of the well-known viscous drag reduction strategy of imposing spanwise wall oscillations to reduce pressure drag contributions in a transitiona…
Quantifying inner-outer interactions in non-canonical wall-bounded flows
Mogeng Li, Woutijn J. Baars, Ivan Marusic +1
We investigate the underlying physics behind the change in amplitude modulation coefficient in non-canonical wall-bounded flows in the framework of the inner-outer interaction mode…
Reynolds-number effects on the outer region of adverse-pressure-gradient turbulent boundary layers
Rahul Deshpande, Aron van den Bogaard, Ricardo Vinuesa +2
We study the Reynolds-number effects on the outer region of moderate adverse-pressure-gradient (APG) turbulent boundary layers (TBLs) and find that their small scale energy reduces…
