【摘要】 通过将结构分析与优化引申到气动设计中,建立了具有弯、扭、掠叶片流场结构分析能力的燃气涡轮气动设计体系,并将这一体系进一步划分为四个子体系。介绍了各子体系的构成与功能,并在流场结构分析与优化子体系中给出了流场结构三个层次的分析框架。更多还原

【Abstract】 A turbine aerodynamic design system is established that is capable for modeling of a bowed - twist - sweep blade with analysis and optimization of the flow field structure applied to the aerodynamic design. The constitutes and functions of four subsystems are introduced and three hierarchies of flow field analysis frame are presented in the analysis and optimization subsystem of flow field structure.更多还原
