Abstract: A fast and accurate method of numerical simulation of nonequilibrium steam condensation flow is developed based on analytical derivation of parameters of Wilson point and transition function method. The nucleating flows in nozzles and cascades are simulated by this method and good agreement is obtained between experiment and calculation. The developed method and code are useful for fast analysis of wet steam flow and design of wet steam turbine stages.
