On the relationship between manipulated inter-scale phase and energy-efficient turbulent drag reduction
Rahul Deshpande, Dileep Chandran, Alexander J. Smits +1
We investigate the role of inter-scale interactions in the high-Reynolds number skin-friction drag reduction strategy reported by Marusic et al. (Nat. Commun., vol. 12, 2021). The…
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…
Evidence that superstructures comprise of self-similar coherent motions in high boundary layers
Rahul Deshpande, Charitha M. de Silva, Ivan Marusic
We present experimental evidence that the superstructures in turbulent boundary layers comprise of smaller, geometrically self-similar coherent motions. The evidence comes from ide…
