| 摘 要： | 根据流体力学中N－S方程对层流的描述，结合经典的力学理论分析，对两相偏心环状管流的相界面提出了严密而科学的力学耦合条件，得到了完整描述偏心环状管流的适定的偏微分方程组。利用计算机仿真技术，得到了两相流中偏心环状层流管流的流动规律，这种规律具有重要的工程应用价值。

| Abstract: | According to N-S equations of hydromechanics and mechanics, the interface coupling equations on eccentric annular pipe flow are put forward,and a system of partial differential equations is obtained. By nu- merical computation,the flowing laws on eccentric annular pipe flow are obtained. In this article,the author gives the establishment process of mathematical model of eccentric annular pipe flow and computational case. |
