ABSTRACT

In this paper, a mathematical model of nucleation and growth of particles and the supercooled supersaturated solution of the fluid based on the theory dropping expandable near the critical point in the channel and the free stream fluid. To account for the effect of fluctuations on the processes of hydrodynamics, mass transfer, phase equilibria and nucleation Used crossover equation of state Kiselyov. To find the fields of temperature, pressure, density and velocity of the flow system used by the Navier-Stokes equations, which is solved by a software package Ansys Fluent. Fluid flow is assumed two-dimensional, axially symmetric, stationary, and viscous compressible.
