摘要: 研究两相流体的界面进入细管时的流动过程.采用有限元方法,在远区用了相似单元方法,在随时变化过程中只对与界面相邻的单元作更动.由此,大大节省了计算工作量.对分界面与管壁的交汇过程设计了算法,算得界膜入口长度的变化过程与实测基本一致,但计算能提供整个流动的细节.

Abstract: The motion of the film separating two fluid phases is studied when it begin to be attracted into a thin pipe. Finite element method, especially the similar element is used. The elements attaching to the film are changed step by step in the calculation. The computed entrancing length variation is consistent with experiments. The computation offers the whole detail of the now.

Key words: Stokes flow, interface, cell motion
