Bubbly drag reduction using a hydrophobic inner cylinder in Taylor-Couette turbulence
Pim A. Bullee, Ruben A. Verschoof, Dennis Bakhuis +4
In this study we experimentally investigate bubbly drag reduction in a highly turbulent flow of water with dispersed air at $5.0 \times 10^{5} \leq \text{Re} \leq 1.7 \times 10^{6}…
Statistics of rigid fibers in strongly sheared turbulence
Dennis Bakhuis, Varghese Mathai, Ruben A. Verschoof +4
Practically all flows are turbulent in nature and contain some kind of irregularly-shaped particles, e.g. dirt, pollen, or life forms such as bacteria or insects. The effect of the…
Rough wall turbulent Taylor-Couette flow: the effect of the rib height
Ruben A. Verschoof, Xiaojue Zhu, Dennis Bakhuis +4
In this study, we combine experiments and direct numerical simulations to investigate the effects of the height of transverse ribs at the walls on both global and local flow proper…
The influence of wall roughness on bubble drag reduction in Taylor-Couette turbulence
Ruben A. Verschoof, Dennis Bakhuis, Pim A. Bullee +3
We experimentally study the influence of wall roughness on bubble drag reduction in turbulent Taylor-Couette flow, i.e.\ the flow between two concentric, independently rotating cyl…
Wall roughness induces asymptotic ultimate turbulence
Xiaojue Zhu, Ruben A. Verschoof, Dennis Bakhuis +4
Turbulence is omnipresent in Nature and technology, governing the transport of heat, mass, and momentum on multiple scales. For real-world applications of wall-bounded turbulence,…
