BROWNIAN COAGULATION OF NANODROPLETS IN A VAPOR–GAS MIXTURE AND THEIR WEIBULL DISTRIBUTION

A nonlinear Brownian coagulation of nanodroplets in a vapor–gas mixture was investigated with the use of their Weibull distribution having a maximum information entropy. An iteration method is proposed for determining the parameters of this distribution which, for the Brownian coagulation, is self-similar in character. The evolution of a system of nanodroplets as a result of their coagulation with retention of the total mass of the liquid in them was calculated. It is shown that, as a result of the coagulation of nanodroplets in a vapor–gas mixture, their number in a unit volume of the mixture can decrease by several orders of magnitude for several milliseconds
