Selection of Criteria and Determination of Their Values for Estimating the Phase Interaction Behavior in Two-Phase Turbulent Jets

The known classifications of two-phase turbulent flows are considered which can be used for development of mathematical models of these flows. The values of a relative diameter of particles and Stokes number are determined, at which a particle size ceases to influence the turbulence characteristics of phases in the two-phase jet. In this case particles can be regarded as a passive impurity, and a mathematical model of a single-phase jet with the variable density can be used.
