摘要: 采用三阶精度的Parabolic Piecewise Method(PPM)方法和Volume of Fluid(VOF)方法相结合,运用Lagrange-Remapping算法,对高压作用下不同形状气腔压缩过程进行了二维高精度数值计算,给出了复杂形状的多流体流场之间的相互作用。此方法可以用来处理界面两边高压力比、高密度比流动以及强剪切滑移运动等问题。Abstract: We have applied the combination of PPM and VOF methods with Lagrange-Remapping algorithm for simulation of the various cavities compressed by the high pressure loading. The physical processes of the multi-fluid interactions are calculated in high accuracy. This method also shows the potential for dealing with the problems of high density or high pressure ratio flows.
