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…

Measurements of non-linear energy transfer in canonical and drag-reduced turbulent boundary layers
Max W. Knoop, Bas W. van Oudheusden, Rahul Deshpande
Three-dimensional particle-tracking velocimetry (3D-PTV) measurements were used to compute the spectral transport of the Reynolds-stress tensor. The experimental framework is valid…

Passive transverse forcing of turbulent boundary-layer flow using sinusoidal surface grooves
Max W. Knoop, Bas W. van Oudheusden, Luuk Pelkmans +1
A surface geometry consisting of parallel, meandering streamwise grooves has been experimentally studied as an alternative means of passive transverse forcing of turbulent boundary…
