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

Zusammenfassung

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.
