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,…
