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…
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…
A bouncing oil droplet in a stratified liquid and its sudden death
Yanshen Li, Christian Diddens, Andrea Prosperetti +3
Droplets can self-propel when immersed in another liquid in which a concentration gradient is present. Here we report the experimental and numerical study of a self-propelling oil…
Microdroplets nucleation by dissolution of a multicomponent drop in a host liquid
Huanshu Tan, Christian Diddens, Ali Akash Mohammed +4
Multicomponent liquid drops in a host liquid are very relevant in various technological applications. Their dissolution or growth dynamics is complex. Differences in solubility bet…
Bulk scaling in wall-bounded and homogeneous vertical natural convection
Chong Shen Ng, Andrew Ooi, Detlef Lohse +1
Previous numerical studies on homogeneous Rayleigh-Bénard convection, which is Rayleigh-Bénard convection (RBC) without walls, and therefore without boundary layers, have revealed…
Changes in the boundary-layer structure at the edge of the ultimate regime in vertical natural convection
Chong Shen Ng, Andrew Ooi, Detlef Lohse +1
In thermal convection for very large Rayleigh numbers (), the thermal and viscous boundary layers (BL) undergo a transition from a classical state to an ultimate state. In the…
