Rotating Turbine Aerodynamic Design

The work of this thesis is financially supported by the aero fund project. The main purpose is to study the aerodynamics design technology of counter-turbine, to find the question differing from the aerodynamics design of general turbine, and to provide theoretical basis for development of aeroengine.First, the design method for the counter-turbine meridional flow is developed in the present thesis, and one 1+1 type counter-turbine is designed using this method. Then, a blade profile design program is accomplished by means of center-streamline. With this program, the blade suit for flow parameters that was obtained from the meridional-flow program is designed. Finally, the flow field of the cascade of the counter-turbine is simulated using the CFD program. The CFD program is based on the Jameson cell-centered finite volume method.To demonstrate the method developed in this thesis, the results obtained in this paper are compared with the results presented in other references, and good coherence is found.
