【摘要】 本文根据文献[1]提出的三元流动通用理论,使用两类流面的交替迭代求解三元流场的方法,在已有的S₁和S₂流面计算机程序的基础上,建立起一个数值求解叶轮机械三元流场的完整体系。本文算例的收敛过程和计算结果充分证明了用两类流面交替迭代方法求解三元流场的有效性。更多还原

【Abstract】 Based on Wu’s general three-dimensional turbomachine flow theory. A complete three-dimensional computing sistem has been established.There are four basic codes in this system: the code of central S2 stream surface; the code of S1 stream surface of revolution; the code of general S2 stream surface, and the code of general (arbitrary twist) S1 stream surface. The first two codes are used only once to establish the initial values of the three-dimensional flow field, but the other two codes are used successively until the convergence is reached.As a example, a complete three-dimensional flow analysis of a axial-compressor stator has been conducted using this computing system and the satisfactory results have been achie-ned.更多还原
