Abstract

Calculation results for no equilibrium wet steam flow in axisymmetric expanding nozzle. Condensation instability for pure spontaneous condensation (without heterogeneous nucleus) may be observed. Stabilizing influence of growing heterogeneous nucleus concentration on the flow, which caused the change of regime into the stable flow with the rise of pressure, is shown
