| Abstract: | The prominently complex effect of control stage with partial admission of stream turbine influences not only the aerodynamic performance and the efficiency,but also the safety of unit.Based on the 3D viscous N-S equations,with the application of structural hexahedron mesh and Finite volume method,the numerical model for control stage of 150MW steam turbine with partial admission is constructed and the nature of control stage flow is investigated detailed.Results show that loss of flow in admission room is c... |
