An Eulerian numerical method of modeling wet steam flows is proposed. The governing equations for the condensed matter are derived from the kinetic equation for the droplet distribution function by an averaging procedure. The developed method is applied to a computer simulation of steady as well as nonsteady transonic flows of subcooled steam under conditions of spontaneous (homogeneous) condensation. The main purpose of the work is the comparative analysis of various approaches to the simulation of droplets radii spectrum evolution. The results of quasi-one-dimensional and two-dimensional modeling studies are discussed also.
