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…
Experimental assessment of square wave spatial spanwise forcing of a turbulent boundary layer
Max W. Knoop, Friso H. Hartog, Ferdinand F. J. Schrijer +3
We present an experimental realisation of spatial spanwise forcing in a turbulent boundary layer flow, aimed at reducing the frictional drag. The forcing is achieved by a series of…
First free-flight flow visualisation of a flapping-wing robot
Matěj Karásek, Mustafa Percin, Torbjørn Cunis +4
Flow visualisations are essential to better understand the unsteady aerodynamics of flapping wing flight. The issues inherent to animal experiments, such as poor controllability an…
