摘要
采用了自适应的非结构网格和基于有限体积法的二阶Godunov格式 ,数值模拟了在激波作用下两种不同密度流体的交界面的演化过程 .着重讨论了Richtmyer Meshkov不稳定性以及斜压效应在交界面演化过程中的作用 ,并给出了交界面的扰动增长率 .
An approach combining the adaptive unstructured grids and the high order Godunov type scheme based on the finite volume method is applied to simulate the evolution of the interface between two layers of fluid with different densities. The research focuses on Richtmyer Meshkov instability and baroclinic effect in the evolution of the interface. The perturbation growth rates of the interface are also presented. [
