| contents | We investigate the blowup criterion of the barotropic compressible viscous fluids for the Cauchy problem, Dirichlet problem and Navier-slip boundary condition. The main novelty of this paper is two-fold: First, for the Cauchy problem and Dirichlet problem, we prove that a strong or smooth solution exists globally, provided that the vorticity of velocity satisfies Serrin's condition and the maximum norm of the divergence of the velocity is bounded. Second, for the Navier-slip boundary condition, we show that if both the maximum norm of the vorticity of velocity and the maximum norm of the divergence of velocity are bounded, then the solution exists globally. In particular, this criterion extends the well-known Beale-Kato-Majda's blowup criterion for the 3D incompressible Euler equations (Comm. Math. Phys. 94(1984):61-66) to the 3D barotropic compressible Navier-Stokes equations, and can be regarded as a complement for the work by Huang-Li-Xin (Comm. Math. Phys. 301(2011):23-35). The vacuum is allowed to exist here. |
