报告摘要:
In this talk, we study a simplified diffuse-interface model for two-phase fluids. The system couples the compressible Navier–Stokes equations, which govern the evolution of the density and velocity field, with the Allen–Cahn equation for the order parameter. We establish a relative energy inequality for the system, from which the weak–strong uniqueness principle follows. Furthermore, we analyze the low Mach number limit and derive the corresponding incompressible model.
