Kinetics of formation of a new phase nuclei in confined systems is
complex process due to depletion of a parent phase.
As a consequence the critical size of clusters increases similarly as a
nucleation barrier.
Supercritical clusters (formed during phase transition process) can
become undercritical, which has impact on nucleation. We have
numerically solved a set of nucleation equations to determine basic
characteristics of this process: time dependence of the
size distribution of nuclei,
nucleation rate and supersaturation
in dependence on the initial
supersaturation and volume of the parent phase for formation of droplets
from supersaturated vapor.
