| 摘 要： | 圆截面光滑直管内充分发展的两流体同心环状流的线性稳定性研究不仅具有重要的学术意义，而且在预测两相流型转换方面也有着重要应用.本文评述了该流动构型的线性稳定性研究进展，着重分析了该流动构型的失稳机制及其与两相流型转换间的关系，并针对微重力气-液两相流地面模拟实验问题，探讨了今后需要着重研究的若干方面.

| Abstract: | Apart from its clear academic relevance, the study on the stability of fully developedconcentric core-annular flow in straight circular pipes is motivated by its technological importancewith applications such as in the prediction of two-phase flow pattern transitions. This paperpresents a detailed revier on the progress of the lineax stability analysis of its flow configuration.The discussion centres on the relationship between the instability mechanism and the two-phaseflow pattern transitions. Some important topics in connection with the simulated microgravityexperiments on two-phase flow patterns in the territorial normal gravity environment are alsopointed out for the future research. |
