An empirical approach to the nucleation of sulfuric acid droplets in the atmosphere
nucleation Gibbs energy aerosol microphysics
2015/9/16
We use quantum mechanical evaluations of the Gibbs free energy of the hydrates of sulfuric acid, H2SO4. nH2O and (H2SO4)2
. nH2O to evaluate an empirical surface tension for sulfuric acid-water clust...
TURBULENT TRASITION IN ELECTROMAGNETICALLY LEVITATED LIQUID METAL DROPLETS
TURBULENT TRANSITION ELECTROMAGNETICALLY LEVITATED LIQUID METAL DROPLETS
2014/10/23
The condition of fluid flow has been proven to have a significant influence on a wide variety of material processes. In electromagnetic levitation (EML) experiments, the internal flow is driven primar...
Statistical Outliers and Dragon-Kings as Bose-Condensed Droplets
Statistical outliers Dragon-kings Physics and society Complex systems Bose-Einstein condensation Zipf law Power law
2012/6/5
A theory of exceptional extreme events, characterized by their abnormal sizes compared with the rest of the distribution, is presented. Such outliers, called "dragon-kings", have been reported in the ...
Viscous coalescence of droplets -- a Lattice Boltzmann study
Viscous coalescence of droplets Lattice Boltzmann study Fluid Dynamics
2012/5/29
The coalescence of two resting liquid droplets in a saturated vapor phase is investigated by Lattice Boltzmann simulations in two and three dimensions. We find that, in the viscous regime, the bridge ...

2011/8/17
Abstract: The equilibrium properties of polymer droplets on a soft deformable surface are investigated by molecular dynamics simulations of a bead-spring model. The surface consists of a polymer brush...
Particle tracking for polydisperse sedimenting droplets in phase separation
particle tracking image processing droplet size distribution phase separation
2011/8/3
Abstract: 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...
Thermocapillary migration and interactions of two nondeformable droplets
Thermocapillary migration nondeformable
2011/8/29
A numerical study on interactions of two spherical drops in thermocapillary migration in microgravity is presented. Finite-difference methods were adopted and the interfaces of drops were captured by ...
Glycine in aerosol water droplets: a critical assessment of Köhler theory by predicting surface tension from molecular dynamics simulations

Controlled Buckling Crumpling of Nanoparticle-Coated Droplets
2010/11/24
We introduce a new experimental approach to study the structural transitions of large numbers
of nanoparticle-coated droplets as their volume is reduced. We use an emulsion system
where the disperse...
