DSMC simulation of clusterization in the gas

DSMC models of cluster formation based on the size-corrected classical nucleation theory (CNT) and on the kinetic theory are used for simulation of stationary water condensation process. The relaxation of the size distribution function is calculated for the spatially homogeneous case, where the water monomer parameters are kept constant. Simulation results obtained with the use of these two models demonstrate essential difference. Such difference is explained by the one-temperature nature of the CNT-oriented model.
