【摘要】 对气液两相弹状流中液弹和气泡合并情况进行了研究．得出最小稳定液弹长度是液弹尾部达到充分发展的速度分布所需的长度．通过对液弹内弥散气泡的统计分析，得出稳定液弹内不存在直径大于５ｍｍ的气泡．借助流动可视化技术，对弹状流中各种尺寸气泡的合并情况进行了描述，得出小气泡之间的合并为二元式合并，而小气泡与大气泡之间的合并是非二元式合并．更多还原

【Abstract】 The liquid slug in gas liquid slug flow is studied in this paper. The minimum stable liquid slug length is the length required to obtain a fully developed velocity profile at the rear of the liquid slug. It is also concluded that diameters of dispersed bubbles in air water stable liquid slugs are well below 5 mm. The coalescence of bubbles is described by means of rapidly advancing flow visualization technique.更多还原
