| Abstract: | In order to improve the convergence and accuracy of turbine flow field simulation, based on the flow field simula.tion technology of the moving grid, a two-step method with first steady-state and then transient calculation of turbine tran.sient flow field simulation is discussed. The calculation results show that there is a step of flow field parameters caused bythe conservation of calculation equations on the sliding interface between rotor and stator, and the variation trend of flowfield parameters is consistent with the analysis results of one-dimensional isentropic flow theory. |
