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.
- jet stability,
- Chebyshev collocation,
- Floquet theory,
