This monograph discusses the essential principles of the evaporationprocess by looking at it at the molecular and atomic level.In the first part methods of statistical physics, physical kinetics andnumerical modeling are outlined including the Maxwell’s distributionfunction, the Boltzmann kinetic equation, the Vlasov approach, and theCUDA technique.The distribution functions of evaporating particles are then defined.Experimental results on the evaporation coefficient and the temperaturejump on the evaporation surface are critically reviewed and compared tothe theory and numerical results presented in previous chapters.The book ends with a chapter devoted to evaporation in differentprocesses, such as boiling and cavitation.This monograph addressesgraduate students and researchers working on phase transitions andrelated fields.
