摘要

同轴射流广泛应用于航空航天领域，目前基于线性机制的理论模型对预测射流波包和噪声普遍存在局限性，非线性效应已成为研究热点。本文通过在线性抛物化稳定性方程（PSE）右端项中加入外部激励项，研究了亚声速同轴射流中非线性对波包演化的作用。当前工作主要聚焦于考察同轴射流中的波包特性，因为其存在两个剪切不稳定模态。基于同轴射流的基本流，采用求解线性PSE构建了线性波包，进一步通过求解伴随PSE方程得到了总体扰动能量对外部激励的敏感性。结果表明敏感性区域和流动较大响应区域均对应于内外临界层附近，且二者对外部激励均十分敏感，在下游区域可以看出，内外两个失稳模态之间存在一定程度的相互作用。最后，采用伴随优化的方法获得了关于外模态的最优激励，且施加最优激励之后波包得以更快速的增长。

Abstract

Coaxial jets are widely applied in Aeronautics and Astronautics. However great limitation generally exists for predicting wavepackets and noise by theoretical models based on linear mechanisms

and the effect of nonlinearity has become a research hotspot recently. The effects of nonlinearity on wavepackets in subsonic coaxial jets with different velocity ratios are studied by adding external harmonic forcing to linear Parabolized Stability Equations (PSE). The present work focuses on investigating wavepacket model of coaxial jets due to the fact that there are two distinct shear layer modes. With the mean flow of coaxial jets

the linear model of wavepackets based on PSE is constructed

while the sensitivity of total disturbance energy with respect to external forcing is obtained by solving the adjoint PSE (APSE). The results show that the sensitivity and flow response reach their maximum around the inner and outer critical layers

both of them turn out to be sensitive to external forcing

while the mutual influence between two instability modes can be identified in the downstream region. Finally

the optimal forcing for the outer mode is obtained using an APSE based optimization methodology

giving rise to more rapid growth of wavepackets.
