摘要

研究了两相(液气)流在垂直圆形截面的同轴管无限系内的轴对称层流问题。对解析解的分析表明，随着气流速度的增加，出现了截留状态(此时介质在界面处的速度为零)和驱油状态(此时液体体积流量为零)。人们发现，与冷介质相比，在加热介质中，这些状态发生在较低的气体流速值下。

Axisymmetric laminar flow of two-phase medium inside the system of two coaxial pipes

The problem of the axisymmetric laminar flow of a two-phase (liquid-gas) flow inside the infinite system of coaxial tubes with a circular cross-section located vertically is considered. Analysis of the analytical solution showed that increase in velocity of the gas flow leads to the appearance of the hold-up regime (then the velocity of media at the interface is zero) and flooding regime (when volume flow of liquid is zero). It is discovered that these regimes occur at lower values of the velocity of the gas flow for the heated medium in comparison with the cold medium.
