CALCULATION AND ANALYSIS OF KINETIC CHARACTERISTICS OF DROPLET NUCLEATION ON THE MACROSCOPIC CONDENSATION NUCLEI UNDER THE CONDITIONS OF GRADUAL CREATION OF THE METASTABLE STATE IN VAPOR

The algorithm of the calculations of all principal kinetic characteris tics of nucleation of supercritical droplets under the gradual creatio n of the metastable state in vapor (total number of emerging droplets, beginning time and duration of droplet emergence, and dimensions of d roplets) was formulated. It was shown that under the given properties of the vapor-gas medium, the liquid condensing from it, as well as at given dimensions of condensation nuclei, the algorithm allows us to co ver the entire range of the characteristic time of the creation of the metastable state in vapor and that of the initial concentration of th e condensation nuclei admitted by the conditions of the theory applica bility. It was elucidated that the macroscopicity of condensation nucl ei results in more rigorous conditions of applicability. Based on the algorithm, numerical calculations demonstrated the ability of the theo ry proposed to make practical prospects in a rather wide range of exte rnal parameters of the theory. The theory was generalized for the case of the gradual creation, arbitrarily changing in time, of the metasta ble state in vapor.
