| Abstract: | Unstructured algorithm is employed in this paper to simulate the complex flow field inside high pressure combined valve of a 600MW steam turbine. Different stem lifts are considered and the flow structures are discussed in detail. Numerical calculations are compared with model experimental results. Some explanations of the special phenomena observed in experiments are presented. |
