This work combines Navier-Stokes-Korteweg dynamics and rare event techniques to investigate the transition pathways and times of vapour bubble nucleation in metastable liquids under homogeneous and heterogeneous conditions. The nucleation p...

Motivated by the need for a better understanding of marine plastic transport, we experimentally investigate finite-size particles floating in free-surface turbulence. Using particle tracking velocimetry, we study the motion of spheres and d...

Refraction is the predominant mechanism causing spatially inhomogeneous surface gravity wave fields. However, the complex interplay between depth- and current-induced wave refraction remains poorly understood. Assuming weak currents and slo...
On the role of unsteadiness in impulsive-flow-driven shear instabilities: precursors of fragmentation [0.03%]

Shear instabilities at the interface of two fluids, such as classical Kelvin-Helmholtz instability (KHI), is the precursor of interface destabilization, leading to fluid fragmentation critical in a wide range of applications. While many ins...

Low inertia, pulsatile flows in highly distensible, viscoelastic vessels exist in many biological and engineering systems. However, many existing works focus on inertial, pulsatile flows in vessels with small deformations. As such, here we ...
Fluid dynamics in intracranial aneurysms treated with flow-diverting stents: effect of multiple geometrical parameters [0.03%]

Characterizing the haemodynamics in intracranial aneurysms is of high interest as it impacts aneurysm growth, rupture and treatment, especially with flow-diverting stents (FDS). Flow in these geometries is known to depend on the Dean, Reyno...
Vapour bubbles produced by long-pulsed laser: a race between advection and phase transition [0.03%]
长脉冲激光产生的气泡：对流与相变的竞赛

Xuning Zhao et al.
Vapor bubbles produced by long-pulsed laser often have complex non-spherical shapes that reflect some characteristics of the laser beam. The transition between two commonly observed shapes - namely, a rounded pear-like shape and an elongate...
The joint effects of planetary β, topography and friction on baroclinic instability in a two-layer QG model [0.03%]

The quasi-geostrophic two-layer model is a widely used tool to study baroclinic instability in the ocean. One instability criterion for the inviscid two-layer model is that the potential vorticity (PV) gradient must change sign between the ...

Topological properties of the spectrum of shallow-water waves on a rotating spherical body are established. Particular attention is paid to spectral flow, i.e. the modes whose frequencies transit between the Rossby and inertia-gravity waveb...
Microrheometric study of damage and rupture of capsules in simple shear flow [0.03%]
微米流变学研究简单剪切流动中胶囊的损伤和破裂现象

C El Mertahi et al.
Capsules, which are potentially-active fluid droplets enclosed in a thin elastic membrane, experience large deformations when placed in suspension. The induced fluid-structure interaction stresses can potentially lead to rupture of the caps...
