提出了一种结合真实的鬼流体方法（RGFM）的波前跟踪方法，用于模拟二维可压缩流动中的流体界面。本文沿着界面法线方向构造了黎曼问题，并利用相应的黎曼解跟踪流体界面。界面边界条件由RGFM定义，流体界面由几个连接的标记点显式跟踪。Riemann解也直接用于更新RGFM中界面两侧的流动状态。为了验证新方法的准确性和计算能力，采用Euler方程对气泡平流、Sod管、激波与气泡相互作用、Richtmyer-Meshkov不稳定性和气-水界面等问题进行了数值模拟。计算结果也与以前的计算研究进行了比较，它显示出良好的协议，包括可压缩的气体-水系统的大密度差。
A front tracking method combined with the real ghost fluid method (RGFM) is proposed for simulations of fluid interfaces in two-dimensional compressible flows. In this paper the Riemann problem is constructed along the normal direction of interface and the corresponding Riemann solutions are used to track fluid interfaces. The interface boundary conditions are defined by the RGFM, and the fluid interfaces are explicitly tracked by several connected marker points. The Riemann solutions are also used directly to update the flow states on both sides of the interface in the RGFM. In order to validate the accuracy and capacity of the new method, extensive numerical tests including the bubble advection, the Sod tube, the shock-bubble interaction, the Richtmyer-Meshkov instability and the gas-water interface, are simulated by using the Euler equations. The computational results are also compared with earlier computational studies and it shows good agreements including the compressible gas-water system with large density differences.
