Abstract
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.
