摘要

摘要: 基于周期脉动速度激励下气液同轴射流的数学模型，运用线性稳定性理论，采用Chebyshev配点法和Floquet理论，将含周期脉动分层流的Floquet稳定性分析扩展到大密度比的情况．研究了液铝-氮气射流的参数共振特性，分析了不同的物理参数对系统稳定性的影响，计算了实验工况并和实验结果进行了比较．

Abstract: By the numerical simulation of basic flow,Floquet stability analyis of interfacial flow with periodic fiuctuation into lage density ratio range were extended.The stability of a liquid aluminum jet in a coaxial nitrogen stream with velocity fiuctuation Was investigated by Chebyshev collocation method and the Floquet.The parametric resonance of the jet and the influences of different physical parameters on the instability were discussed.The results show qualitative agreement with the experimental data available.
