Global well-posedness of 2D compressible Navier-Stokes equations with large data and vacuum
arXiv:1202.1382
Abstract
In this paper, we study the global well-posedness of the 2D compressible Navier-Stokes equations with large initial data and vacuum. It is proved that if the shear viscosity is a positive constant and the bulk viscosity is the power function of the density, that is, $ł(\r)=\r^\b$ with $\b>3$, then the 2D compressible Navier-Stokes equations with the periodic boundary conditions on the torus admit a unique global classical solution which may contain vacuums in an open set of . Note that the initial data can be arbitrarily large to contain vacuum states.
