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MOF-MMALE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 multi-material and large deformation flow with high accuracy and good interface resolution in axisymmetric geometry. |
