Catastrophic phase inversion in high-Reynolds number turbulent Taylor--Couette flow
Dennis Bakhuis, Rodrigo Ezeta, Pim A. Bullee +4
Emulsions are omnipresent in the food industry, health care, and chemical synthesis. In this Letter the dynamics of meta-stable oil-water emulsions in highly turbulent ($10^{11}\le…
Heat transfer enhancement in Rayleigh-Bénard convection using a single passive barrier
Shuang Liu, Sander G. Huisman
In this numerical study on Rayleigh-Bénard convection we seek to improve the heat transfer by passive means. To this end we introduce a single tilted conductive barrier centered in…
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}…
Double maxima of angular momentum transport in TC turbulence
Rodrigo Ezeta, Francesco Sacco, Dennis Bakhuis +5
We use experiments and direct numerical simulations to probe the phase-space of low-curvature Taylor--Couette (TC) flow in the vicinity of the ultimate regime. The cylinder radius…
Effect of axially varying sandpaper roughness on bubbly drag reduction in Taylor-Couette turbulence
Pim A. Bullee, Dennis Bakhuis, Rodrigo Ezeta +4
We experimentally investigate the influence of alternating rough and smooth walls on bubbly drag reduction (DR). We apply rough sandpaper bands of width between and…
Using ray-traversal for 3D particle matching in the context of particle tracking velocimetry in fluid mechanics
Mickael Bourgoin, Sander Huisman
An innovative method based on the traversal of rays, originating from detected particles, through a three-dimensional grid of voxels is presented. The methodology has as main advan…
