摘　　要：弹状流是垂直管内气液两相上升流中的一种重要流型。本文从相对坐标系的质量与动量衡算出发,对弹状气泡与下落液膜流动进行分析,建立了相应的计算公式。本文也是完整的弹状流数学模型的一部分。Slug flow is one important flow patten for upward gas-liquid two-phase flow in vertical tube. Starting from mass and momentum balance in special reference coordinate system, the flow pattern of slug bubble and downward liquid film around the moving bubble are analyzed, and the corresponding formula, which is one part of a newly developed mathematical model for slug flow, is given.

关 键 词：化工过程 气液流动 弹状流 垂直管
