Characterizing the turbulent drag properties of rough surfaces with a Taylor--Couette setup
Pieter Berghout, Pim A. Bullee, Thomas Fuchs +5
Wall-roughness induces extra drag in wall-bounded turbulent flows. Mapping any given roughness geometry to its fluid dynamic behaviour has been hampered by the lack of accurate and…
The large-scale footprint in small-scale Rayleigh-Bénard turbulence
Pieter Berghout, Woutijn Johannes Baars, Dominik Krug
Turbulent convection systems are known to give rise to prominent large scale circulation. At the same time, the `background' (or `small-scale') turbulence is also highly relevant a…
Calculation of the mean velocity profile for strongly turbulent Taylor--Couette flow and arbitrary radius ratios
Pieter Berghout, Roberto Verzicco, Richard J. A. M. Stevens +2
Taylor--Couette (TC) flow is the shear-driven flow between two coaxial independently rotating cylinders. In recent years, high-fidelity simulations and experiments revealed the sha…
Controlling secondary flow in Taylor-Couette turbulence through spanwise-varying roughness
Dennis Bakhuis, Rodrigo Ezeta, Pieter Berghout +7
Highly turbulent Taylor-Couette flow with spanwise-varying roughness is investigated experimentally and numerically (direct numerical simulations (DNS) with an immersed boundary me…
Direct numerical simulations of Taylor--Couette turbulence: the effect of sand grain roughness
Pieter Berghout, Xiaojue Zhu, Daniel Chung +3
Progress in roughness research, mapping any given roughness geometry to its fluid dynamic behaviour, has been hampered by the lack of accurate and direct measurements of skin-frict…
