When a binary fluid demixes under a slow temperature ramp, nucleation, coarsening and sedimentation of droplets lead to an oscillatory evolution of the phase-separating system. The advection of the sedimenting droplets is found to be chaotic. The flow is driven by density differences between two phases. Here, we show how image processing can be combined with particle tracking to resolve droplet size and velocity simultaneously. Droplets are used as tracer particles, and the sedimentation… 
Crossing the bottleneck of rain formation
The demixing of a binary fluid mixture, under gravity, is a two stage process. Initially droplets, or in general aggregates, grow diffusively by collecting supersaturation from the bulk phase.
Lagrangian tracking of colliding droplets
Abstract We introduce a new Lagrangian particle tracking algorithm that tracks particles in three dimensions to separations between trajectories approaching contact. The algorithm also detects low
A diffusion-induced transition in the phase separation of binary fluid mixtures subjected to a temperature ramp
Demixing of binary fluids under slow temperature ramps shows repeated waves of nucleation which arise as a consequence of the competition between generation of supersaturation by the temperature ramp
Ripening and focusing of aggregate size distributions with overall volume growth
We explore the evolution of the aggregate size distribution in systems where aggregates grow by diffusive accretion of mass. Supersaturation is controlled in such a way that the overall aggregate
Frequency-lock reactive control of a separated flow enabled by visual sensors
AbstractIn this study, a physical-based algorithm is used to control the separated flow downstream of a backward-facing step. It is well known that the spatial extent of the re-circulation bubble can
The journey of hydrogen to quantized vortex cores
Nanoscale hydrogen particles in superfluid helium track the motions of quantized vortices. This provides a way to visualize turbulence in the superfluid. Here, we trace the evolution of the hydrogen


Interfacial dynamics in demixing systems with ultralow interfacial tension
We report measurements on fluid–fluid phase separation in a colloid–polymer mixture, which can be followed in great detail due to the ultralow interfacial tension. The use of the real-space
A reactive-flow model of phase separation in fluid binary mixtures with continuously ramped temperature
We suggest to revisit the phase separation of binary mixtures subjected to a sustained change of temperature from the point of view of reactive flows. Exploiting this new perspective, we describe the
Oscillations in the dynamics of temperature-driven phase separation
We examine the dynamics of the phase separation of a single phase of water-in-oil microemulsion droplets towards a phase of smaller droplets coexisting with a water-rich phase. Oscillations are
Phase separation in binary fluid mixtures with continuously ramped temperature
This work considers the demixing of a binary fluid mixture, under gravity, which is steadily driven into a two–phase region by slowly ramping the temperature, and examines the interplay of two competing nonlinearities.
Asymmetric oscillations during phase separation under continuous cooling: A simple model.
This work investigates the phase separation of binary mixtures under continuous cooling using the Cahn-Hilliard equation including the effect of gravity using a simple model and predicts an oscillatory variation of turbidity.

Stable diffusive demixing can only be achieved when special precautions are taken in experiments on real mixtures, and the recent observations on complex dynamical behavior in such systems should be considered as a new challenge for understanding generic features of phase-separating systems.
Collisions of Small Drops in a Turbulent Flow. Part I: Collision Efficiency. Problem Formulation and Preliminary Results
A mathematical approach to the calculation of the collision efficiency between droplets within a turbulent flow is suggested. The problem of drops’ hydrodynamic interaction is reconsidered taking
Emulsification in binary liquids containing colloidal particles: a structure-factor analysis.
An image-analysis method that relies on structure factors obtained from discrete Fourier transforms of individual frames in confocal image sequences to clarify the link between quench conditions and resulting microstructure, paving the way for tailor-made particle-stabilized emulsions from binary liquids.
Theory of nucleation and growth during phase separation
We present a new model for the entire process of phase-separation that combines steady-state homogeneous nucleation theory with the classical Lifshitz-Slyozov mechanism of ripening, modified to
Review of Particle–Turbulence Interactions and Consequences for Cloud Physics
Abstract This paper summarizes recent progress on particle—turbulence interaction and discusses the possible implications for cloud physics. The subject is of considerable current interest as
