Evaporation of S from Liquid Fe–C–S Alloy

Evaporation of a Liquid Droplet

Two idealized models for the preheat s tage of liquid droplets are ana lyzed theoretically . These models conta in the effects of transie nt heat conduction and evaporati on. It is assumed that the droplet surface a rea decreases linearly with time. This assumption necessitates the solution of mov ing boundary problems . These models, however, do not consider gas-phase mass transport . In the f...

A More Accurate Prediction of Liquid Evaporation Flux

In this work, a more accurate prediction of liquid evaporation flux has been achieved. The statistical rate theory approach, which is recently introduced by Ward and Fang and exact estimation of vapor pressure in the layer adjacent to the liquid–vapor interface have  been used for prediction of this flux. Firstly, the existence of an equilibrium layer adjacent to the liquid-vapor interface ...

Raman thermometry measurements of free evaporation from liquid water droplets.

Recent theoretical and experimental studies of evaporation have suggested that on average, molecules in the higher-energy tail of the Boltzmann distribution are more readily transferred into the vapor during evaporation. To test these conclusions, the evaporative cooling rates of a droplet train of liquid water injected into vacuum have been studied via Raman thermometry. The resulting cooling ...

Direct measurement of ion evaporation kinetics from electrified liquid surfaces

When concentrated solutions of NaI in formamide with electrical conductivities K larger than 1.1 S/m are electrosprayed from a Taylor cone-jet in a vacuum, ions are evaporated at substantial rates from the surface of the meniscus and the drops. This constitutes a new source of ions and nanoparticles, where the relative importance of these two contributions is adjustable. The currents of ions ar...
