摘要
对湍流结构的正交分解与低阶近似进行了探讨 ,并在正交分解的基础上建立了湍流相干结构相干模式的识别方法 .同时 ,还对射流。
The orthogonal decomposition and low dimensional approximation of turbulent structures are investigated, and a pattern identification method based on orthogonal decomposition is suggested. Furthermore, theoretical and experimental results of orthogonal decomposition in jet flow, turbulent boundary layer and channel flow are also analyzed.
