Title: Global weak solution to the viscous two-fluid model with finite energy,
Abstract: In this paper, we prove the existence of global weak solutions to the
compressible two-fluid Navier-Stokes equations in three dimensional space. The
pressure depends on two different variables from the continuity equations.
We develop an argument of variable reduction for the pressure law. This
yields to the strong convergence of the densities, and provides the existence
of global solutions in time, for the compressible two-fluid Navier-Stokes
equations, with large data in three dimensional space.
