This monograph discusses the essential principles of the evaporation process by looking at it at the molecular and atomic level. In the first part methods of statistical physics, physical kinetics and numerical modeling are outlined including the Maxwell's distribution function, the Boltzmann kinetic equation, the Vlasov approach, and the CUDA technique. The distribution functions of evaporating particles are then defined. Experimental results on the evaporation coefficient and the temperature jump on the evaporation surface are critically reviewed and compared to the theory and numerical results presented in previous chapters. The book ends with a chapter devoted to evaporation in different processes, such as boiling and cavitation. This monograph addresses graduate students and researchers working on phase transitions and related fields.

It is established that surface-active substances (SAS), both soluble and insoluble, substantially slow the rate of evaporation of water drops. In the case of insoluble SAS the slowing of evaporation comes down to the creation of a mechanical barrier by SAS molecules, preventing the outlet of water molecules from the surface of the drop. A formula was theoretically obtained, expressing the rate of quasistationary evaporation of a drop of water covered with a layer of insoluble SAS.

The kinetics of vapor-liquid exchange in water are poorly understood, yet may be critically important in predicting changes in Earth's climate and understanding the water isotope record preserved in ice cores . In this thesis we present measurements of the kinetics of water evaporation. In Chapter 1 we review recent work on the subject, including our own liquid microjet technique which has higher precision than other methods. In Chapter 2 we extend our earlier measurements of the evaporation kinetics of H2O by studying pure D2O. We find that the evaporation coefficient, which can be thought of as the percentage of evaporation "attempts" which succeed, is identical for the two isotopomers. We interpret this result using a previously developed transition state theory (TST) model of evaporation, which predicts the respective evaporation coefficients to be equal due to competing energetic and entropic effects. In Chapter 3, we examine the evaporation kinetics of H2O evaporating from 3M ammonium sulfate solution. Ammonium sulfate was selected as it is the largest inorganic component of anthropogenic aerosol in the atmosphere. Again we find that the evaporation coefficient is unchanged relative to pure water. This is consistent with theoretical and experimental studies suggesting that both the ammonium ion and sulfate ion are repelled from the air-water interface, implying that these ions will not directly interact with evaporating water molecules. This result also suggests that inorganic components of atmospheric aerosol are unlikely to significantly affect evaporation kinetics. In Chapter 4 we examine the evaporation kinetics of H2O from 4M sodium perchlorate solution. Perchlorate was selected as it is expected to be strongly enhanced in concentration at the air-water interface, and therefore more likely to directly influence the evaporation process. We find that the evaporation coefficient for this system is ̃25% smaller than that for pure H2O, indicating that the perchlorate ions do indeed impede evaporation. Given experimental evidence for the perchlorate ion slowing the rotational motions of H2O molecules in its first solvation shell, and our TST predictions indicating that the evaporation kinetics of water are highly sensitive to the hindered rotational motions of surface water molecules, we suggest that perchlorate ions at the interface are inhibiting the evaporation of H2O molecules with which they are in direct contact. This result suggests that other surface-enhanced ions may also affect the evaporation kinetics through direct interactions with evaporating molecules and opens several interesting new avenues of study, which are discussed in Chapter 5.

Theories on the evaporation kinetics of liquid droplets and assemblages of droplets were reviewed. The diffusion - controlled evaporation of single droplets was treated under stationary, quasi - stationary, and non - stationary conditions. The extent of the influence on the evaporation rate caused by ventilation, heat transfer, radiation, impurities, and monolayers, was estimated. A general time rate equation for single drop evaporation was proposed. This general equation is based on both the diffusion and the kinetic theories; it remains valid for the entire range of droplet radius and ambient pressure. Further extension of this equation is planned to include the monolayer and impurity effects and to correlate the chemical bonding in liquids to their rate of evaporation. A realistic model for cloud evaporation was proposed. This quasi - dynamic model was shown to be more flexible than any static model since it accounts for the dynamic behavior of clouds and sprays in free atmosphere. (Author).
