兆瓦级S-CO_(2)轴流透平气动设计与分析

Aerodynamic Design and Analysis of a Megawatt Axial S-CO_(2) Turbine

采用自主研发的热力计算程序与高效叶型对兆瓦级S-CO_(2)轴流透平进行了一维气动设计,根据所得结果展开建模造型,并利用FLUENT软件进行了三维气动数值分析,结果表明,研究中采用的一维气动设计方法具备可行性,且设计点气动性能优良,满足设计要求。

A megawatt axial S-CO_(2) turbine is designed by one-dimensional aerodynamic method with the tool of independent development calculation program and high-efficiency blade profile.The numerical analysis is carried out by using FLUENT after modelling of blades.The results indicate that the one-dimensional method is feasible.The S-CO_(2) turbine has good aerodynamic performance and meets the design target with the use of this method.
