MGFM方法在运动固壁边界问题中的应用
MGFM method applied to treat moving solid wall boundaries
反射边界条件是当前流行的处理运动固壁边界的方法，并取得了很大的成功。但应用于有强非线性波作用的情况下，这种方法被发现精度不够高而且容易产生数值过热现象。本文将处理多介质运动边界的MGFM方法推广到处理运动固壁边界。数值实验证明了MGFM方法在处理运动固壁边界上比反射边界条件更为有效。
Reflective boundary condition is a popular way of treating moving solid wall boundaries, and has achieved great success. However, it is found that the method does not work very efficiently when applied to treat a moving wall with strong nonlinear wave interaction. In this work, we extend MGFM method, which treats the multi-fluid interface very successfully, to treat the moving solid wall boundaries. The results show that MGFM method is more effective than the reflective boundary in handling the moving solid wall boundaries.
