水平管弹状流液膜区的流动特性研究

将一维形式的双流体模型用于水平管弹状流的液膜区，导出液膜区截面含液率随距离而变的控制方程，讨论了方程的封闭性并提出壁面和界面阻力的计算方法．对液膜区平均截面含液率的计算结果与前人的测量结果作了比较，分析了影响平均截面含液率的因素．通过对截面含液率、液相流速和气相流速沿长度变化的计算分析，首次提出液膜和气弹都是连续波．

Investigation of Flow Characteristics of Liquid Film in Horizontal Slug Flow

The governing equation for liquid holdup of liquid film via distance was developed by applying one dimensional two fluid model to the film region of horizontal slug flow. The closure of the governing equation was discussed and the methods for calculating wall drag force and interfacial frag force were put forward. The mean liquid holdups of liquid film calculated by the governing equation were compared to the data measured by other authors. The factors that influence liquid holdup of liquid film were analysed. The conclusions that liquid film and gas slug are both continuity waves were first put forward and their effects were analysed.
