建立了毛细管内气液弹状流的数学模型。计算了气泡、薄膜和气泡间液体的速度分布。计算结果与其他研究者的实验数据吻合较好。实验发现的分岔行为的气泡相对于文献中报道的两相混合物的滑移速度的描述和支持的理论。讨论了气泡在小直径死端毛细管中停止的原因。
A mathematical model for the gas-liquid slug flow in a capillary is developed. The velocity profiles in the bubble, film, and interbubble liquid are calculated. The calculated results are in good agreement with the experimental data of other researchers. The experimentally found bifurcational behavior of the slip velocity of bubbles relative to the two-phase mixture reported in the literature is described and supported by the theory. The reasons for which the bubble can stop in a small-diameter dead-end capillary are discussed.
