合成射流控制压气机分离流动研究

Synthetic jet is zero-mass flux jet based on vortex movement. In order to control the separation flow of axial compressor, synthetic jet is imported to the main flow field through profile of blade and casing treatment. The results show that the separation flow is controlled by synthetic jet. The engineering application of synthetic jet is also explored preliminarily. The relationship of synthetic jet and casing treatment is analyzed, and the author point out that the synthetic jet can be considered as novelty casing treatment when the synthetic jet is introduced from casing treatment.
