The dependence of evaporation and crystallization kinetics on dynamic and thermal background

In technical problems there is often the need to simultaneously describe both non-stationary evaporation and non-stationary crystallization of droplets and films. Poor wettability of the wall and high heat fluxes lead to the film rupture and the formation of pools, dry spots, droplets. To date, there are no well-developed methods for calculating crystallization and evaporation in the presence of the factors. Evaporation and crystallization of a drop are shown to fundamentally differ from those of a thin layer. The rate of evaporation prior to crystallization controls the crystallization kinetics. The evaporation and crystallization rates for the film (under identical conditions) are significantly higher than for the drop. The difference in the thickness of the diffusion and dynamic boundary layers affects the evaporation rate of an aquatic salt solution. For correct simulation of evaporation, it is necessary to take into account the thicknesses of the thermal, diffusion and concentration boundary layers.
