Impeller-diffuser interaction:analysis of the unsteady flow structures based on their direction of propagation

现在的学习集中于在一个接近音速的离心的压缩机阶段以内从转子定子相互作用产生的确定的变化的分析。一光谱用于不稳定的流动领域的分析导致很精力充沛的模式的旋转速度的价值。从这些价值，各种各样的结构根据他们导致对涉及相互作用的内在的机制的全面描述的繁殖的方向被分类。

The present study is focused on the analysis of the deterministic fluctuations arising from the rotor-stator interaction within a transonic centrifugal compressor stage. A spectral analysis applied to the unsteady flow field leads to the values of the rotation speed of most energetic modes. From these values, the various structures are classified according to their direction of propagation which leads to a comprehensive description of the underlying mechanisms involved in the interaction.
