| Abstract: | The 1.5 dimensional Euler-equations are constructed on the meridional surface meanline of multi-stage axial-turbine.The effects of blade force,gas viscousity and coolant are considered by adding source terms to the equations.The one-step time-marching TVD-LW scheme is employed to solve the governing equations.Computational results showed that the present method is fast and flexible,and can be used for predicting the turbine aerodynamic characteristics or for turbine aerodynamic optimization. |
