| Abstract: | Based on linear stability theory, parametric resonance of a liquid-gas cylindrical flow with periodic fluctuation in a vertical pipe was discussed by using Floquet theory and Chebyshev collocation method. The effects of different physical parameters on the instability of flow and the properties of parametric resonance were investigated. |

| Keywords: | stability Floquet theory parametric resonance |
