摘　　要：本文对1 kHz激励横向射流对超声速混合中大尺度结构的影响进行了数值模拟。结果显示激励射流可以有效地刺激射流剪切层,使大尺度结构提早形成,对混合有积极影响,使主流和射流充分混合。Numerical investigation of the effect of the transverse 1kHz-excited jet on the large scale structures in supersonic mixing was performed in this study.The results showed that the excited jet could stimulate the jet shear layer and make the large scale structures appear earlier compared to the unexcited jet.The excited jet played the positive role in the supersonic mixing and could make the main flow and jet mix fully.

关 键 词：激励射流 大尺度结构 超声速混合 数值模拟
