Investigation on stability of 3-d supersonic mixing layer and method of enhancing the mixing
超音速混合层稳定性分析及增强混合的研究

A useful method of enhancing the mixing for supersonic mixing layer is improving flow dynamics instability.In this paper,the three-dimensional (3-D) compressible mixing layers with spanwise curvature was discussion.According to analyses of flow dynamics stability,the three dimensional disturbances have lager rate of amplification,have better ability of blending in normal direction of mixing layer and can enhance the mixing for 3-D compressible mixing layer in this compressible mixing layers.This characteristic is also for supersonic and hypersonic mixing layer,which is useful method of enhancing the mixing for supersonic and hypersonic mixing layer.
