摘要
针对基于积分形式的Euler方程组耦合质量组份模型方程而发展的多介质整体ALE方法耗散大的问题,采用基于微分形式的Euler方程组所发展的高分辨率界面反耗散的思想来控制界面处的数值耗散,发展了一种二维平面中积分意义下的耦合质量组份方程和体积组份方程的界面反耗散的高分辨率多介质中心型ALE方法,从而高分辨率地模拟大变形物质界面.
For the large dissipation problem of the multimaterial Global ALE method based on the Euler equation with integral form combined with the mass fraction equation, we use the high resolution anti-difusive idea for interface based on the Euler equation with diferential form to control the numerical difusion at interface, and then we developed a multimaterial cell-centered ALE method based on the Euler equation with integral form combined with the mass fraction equation and volume fraction equation in plane coordinate to simulate the large deformation multimaterial interface with high resolution.
