Abstract:We have studied the Cauchy problem of a compressible immiscible two-phase flow model with a diffuse interface in 3D. The model employed involves coupled Navier-Stokes and Allen-Cahn equations. Under the assumption of small initial perturbations, we prove by energy estimates that there is a global unique strong solution.
