Statistics of the Nucleation Process under the Conditions of Gradual Creation of the Metastable State in Vapor

Statistics of the nucleation process at the gradual creation of the metastable state in vapor under the conditions when sufficiently large number of droplets arises in a vapor–gas system by the end of nucleation stage is studied on the assumption of randomness of the droplet nucleation. The probability distribution for a given number of droplets created in the unit volume of the vapor–gas system by the end of the nucleation stage is constructed. The distribution has the Gaussian form with the dispersion depending on the regime of matter exchange between droplets and vapor. The mean number of nucleated droplets under given conditions coincides (with an accuracy of up to the first-order small values with respect to the relative fluctuations of this value) with the predictions of the theory dealing with the average nucleation rate.
