This present study reported of the CFD simulation of non-equilibrium two-phase flow in a nozzle. The investigation is concentrating on the condensing flow in converging-diverging nozzles which is Skilling nozzle. The significance of this investigation is to analyses the behavior of two-phase flow in the Skilling nozzle using CFD. The simulation is using nozzle instead of turbine blade because the condensation process is assumed to be similar to turbine blade. The Nucleation detection was based on the pressure distribution graph produced by the converging solution. The method of testing of the solution obtained is based on analogy with the previous study.
