| Abstract: | Study of aerodynamic design and analysis on 1 1/2 counter-rotating turbine was applied in this paper.By using the free-vortex design concept based on the streamline curvature method,the aerodynamic parameters of the counter-rotating gas turbine were achieved.The parametric method of turbine profile design was used to design the 2D profile,and the Bezier curvature was used to optimize the 2D profile.The stack technology was used to construct the 3D blade.The CFD software was used to analyze the 2D flow field and the 3Dviscous flow field in turbine. |
