| Abstract: | Based on analytical Wilson point parameters and relative saturation wetness algorithm, the fast and accurate numerical simulation approach for 3D viscous non-equilibrium wet steam flow is developed in this paper. The flow in the initial condensation stage in low-pressure cylinder of a operative steam turbine is simulated and the flow phenomena related with non-equilibrium condensation are analysed. This approach can be an advanced and practical platform for analysis and design of wet steam flow in steam turbine. |
