Mixing induced by a bubble swarm rising through incident turbulence
Elise Alméras, Varghese Mathai, Chao Sun +1
This work describes an experimental investigation on the mixing induced by a swarm of high Reynolds number air bubbles rising through a nearly homogeneous and isotropic turbulent f…
Robustness of heat-transfer in confined inclined convection at high-Prandtl-number
Linfeng Jiang, Chao Sun, Enrico Calzavarini
We investigate the dependency of the magnitude of heat transfer in a convection cell as a function of its inclination by means of experiments and simulations. The study is performe…
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…
