Oblique evaporation and surface diffusion

Nonequilibrium cluster diffusion during growth and evaporation in two dimensions.

The diffusion of growing or evaporating two-dimensional clusters is investigated. At equilibrium, it is well known that the mean square displacement (MSD) of the cluster center of mass is linear in time. In nonequilibrium conditions, we find that the MSD exhibits a nonlinear time dependence, leading to three regimes: (i) during curvature-driven evaporation, the MSD shows a square-root singulari...

Evaporation from the Surface of the Globe

Evaporation and Explosion of Liquid Drops on a Heated Surface

The literature pertinent to various aspects of drop evaporation on a heated surface is reviewed. Both the laser shadowgraphic and direct photographic methods are employed to study thermal stability and flow structures in evaporating drops in all heating regimes. It is revealed that four flow regions exist in stable and unstable type drops at low liquid-film type vaporization regime. As the surf...

Influence of evaporation and exchange reactions at the surface on the evolution of an arbitrary tracer distribution by diffusion

2014 The solution of the equation of one-dimensional diffusion with evaporation of the sample and exchange of the diffusant with the ambient at the surface has been applied to the cases of thick layer diffusion, diffusion from an implantation profile and isotope exchange diffusion.

The rate of evaporation of droplets; evaporation and diffusion coefficients, and vapour pressures of dibutyl phthalate and butyl stearate.

The rate of evaporation of drops of dibutyl phthalate and butyl stearate of radius approx. 0*5 mm. has been studied by means of a microbalance over a range of atmospheric pressures down to approx. 0*1 mm. of mercury. Wide departures from Langm uir’s evaporation formula were found to oceur a t these low pressures, bu t results are in good acoordance with the theory of droplet evaporation advance...
