Coherent structure modulation and recovery in drag-reduced turbulent boundary layers

Traian Bistriceanu, Vyacheslav A. Kovalyov, Pradyumn Mishra +3

Drag reduction is achieved by a steady square-wave forcing of the spanwise wall velocity, based on the experiments in Knoop et al. (Phys. Rev. Fluids, 10, 2025). Particle tracking…
