| 摘 要： | 将双流体模型用于绝热无相的管道气液两相流，依据小扰动线化分析原理，导出了压力波波数Ｋ方程通过对不同空隙率下肉体上压力波小随角频率变化的计算，研究了虚拟质量力和狭义相间阻力对压力波波速及其人色散性的影响。对泡状流和弹状流压力波波速的计算结果与前人的测量结果作了比较，两者符合良好。

| Abstract: | A wavenumber equation of pressure wave was derived for adiabatic gas liquid two phase flow by linearizing the conservation equations of two fluid model. The propagation speeds of pressure waves with various frequencies were solved from the wavenumber equation for different void fractions. The effects of drag force and virtual mass force on propagation and dispersion of pressure wave were investigated. The wave speeds calculated for bubbly flow and slug flow are compared well with data measured by former authers. |
