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…
Experimental investigation of heat transport in homogeneous bubbly flow
Biljana Gvozdic, Elise Almeras, Varghese Mathai +6
We present results on the global and local characterisation of heat transport in homogeneous bubbly flow. Experimental measurements were performed with and without the injection of…
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,…
Dispersion of air bubbles in isotropic turbulence
Varghese Mathai, Sander G. Huisman, Chao Sun +2
Bubbles play an important role in the transport of chemicals and nutrients in many natural and industrial flows. Their dispersion is crucial to understand the mixing processes in t…
