旋转叶轮内部全三维可压缩气动问题有限元统一解法

A unified solution for alternative fully 3-D compressible flows inside rotating impeller with finite element method

本文旨在建立旋转叶轮内部全三维可压缩气体流动问题（正问题、反问题、混合问题）的通用数学模型及其有限元统一解法，将三维正问题分析、叶片的完全三维设计以及三维叶片局部改型融合于同一种计算方法．

A unitied solution method for direct-、inverse-and hybrid - problems for fully three dimensional compressible flow has been established by using a discrete universal mathematic model with three dimensional finite element analysis and finite volume method. This method is generally applicable to the three-dimensional analysis, the three dimensional design, and partial modification of a real blade.
