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。
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.
