Motion in stratified fluids

RV More, AM Ardekani - Annual Review of Fluid Mechanics, 2023 - annualreviews.org
Density stratification due to temperature or salinity variations greatly influences the flow
around and the sedimentation of objects such as particles, drops, bubbles, and small …

On the rising and sinking motion of bouncing oil drops in strongly stratified liquids

JG Meijer, Y Li, C Diddens, D Lohse - Journal of Fluid Mechanics, 2023 - cambridge.org
When an immiscible oil drop is immersed in a stably stratified ethanol–water mixture, the
Marangoni flow on the surface of the drop can experience an oscillatory instability, so that …

Stability analysis of Rayleigh–Bénard–Marangoni convection in fluids with cross-zero expansion coefficient

W Tang, J Wang, D Wu, K Song, L Duan, Q Kang - Physics of Fluids, 2024 - pubs.aip.org
Cross-zero expansion coefficient Rayleigh–Bénard–Marangoni (CRBM) convection refers to
the convective phenomenon where thermal convection with stratified positive and negative …

Buoyancy-driven attraction of active droplets

Y Chen, KL Chong, H Liu, R Verzicco… - Journal of fluid …, 2024 - cambridge.org
For dissolving active oil droplets in an ambient liquid, it is generally assumed that the
Marangoni effect results in repulsive interactions, while the buoyancy effects caused by the …

Thermophilic Behavior of Heat-Dissociative Coacervate Droplets

Y Kim, Y Zheng - Nano Letters, 2024 - ACS Publications
In exploring the genesis of life, liquid–liquid phase-separated coacervate droplets have
been proposed as primitive protocells. Within the hydrothermal hypothesis, these droplets …

Dynamics of a silicone oil drop submerged in a stratified ethanol-water bath

MA Herrada, JM Montanero, L Carrión - Physical Review E, 2023 - APS
We analyze numerically the Marangoni flow around an immiscible droplet submerged in a
stably stratified mixture of ethanol and water. The linear stability analysis shows that the …

Enhanced bubble growth near an advancing solidification front

JG Meijer, D Rocha, AM Linnenbank… - arXiv preprint arXiv …, 2024 - arxiv.org
Frozen water might appear opaque since impurities or gas bubbles can get trapped in the
ice during the freezing process. The latter nucleate and then grow near the advancing …

[HTML][HTML] Bifurcation tracking on moving meshes and with consideration of azimuthal symmetry breaking instabilities

C Diddens, D Rocha - Journal of Computational Physics, 2024 - Elsevier
We present a black-box method to numerically investigate the linear stability of arbitrary
multi-physics problems. While the user just has to enter the system's residual in weak …

RESEARCH PROGRESS ON THE MARANGONI INSTABILITY OF A DROP/BUBBLE IMMERSED IN LINEARLY STRATIFIED LIQUIDS

L Yanshen - Chinese Journal of Theoretical and Applied …, 2024 - lxxb.cstam.org.cn
Marangoni instabilities can emerge when a liquid interface is subjected to a temperature or
concentration gradient. It has been extensively studied due to its wide relevance in industrial …
