摘要

在本文中，我们考虑了两种不相溶可压缩粘性流体的扩散界面模型的奇异极限问题。通过相对熵方法，我们得到了在初始数据准备充分和极限密度相同的情况下，低马赫数极限对不可压缩流体相应系统的收敛结果。

Low Mach number limit of a diffuse interface model for two-phase flows of compressible viscous fluids

In this paper, we consider a singular limit problem for a diffuse interface model for two immiscible compressible viscous fluids. Via a relative entropy method, we obtain a convergence result for the low Mach number limit to a corresponding system for incompressible fluids in the case of well-prepared initial data and same densities in the limit.
