中文摘要：

推导了轴对称几何下的MOF（Moment of Fluid）界面重构,将其与多介质ALE方法相耦合,形成MOFMMALE方法,并应用于多介质大变形流动问题的数值模拟研究。数值算例表明,耦合MOF界面重构的多介质ALE方法是求解多介质大变形流动问题的有效手段,并且具有很好的界面精度和分辨率。

英文摘要：

Moment of fluid （MOF） interface reconstruction is extended to axisymmetric geometry, and coupled with multi-material Arbitrary Lagrangian-Eulerian （MMALE） method, called MOF-MMALE method. MOF-MMALE method is applied to multi-material large deformation fluid flow problems. The numerical examples show that MOF-MMALE method is an effective way to simulate problems of multimaterial and large deformation flow with high accuracy and good interface resolution in axisymmetric geometry.
