| Abstract: | A fully Eulerian model was developed to investigate the wet steam flow with spontaneous condensation. The virial status equation was implemented in this model to count the difference of properties between vapor and perfect gas. A numerical shaulation was performed for the wet steam condensing flow in a turbine cascade. The comparison between numerical results and experimental measurements shows that the model is accurate and can be extend to calculation of 3D wet steam condensing flow. |
