Global Solutions to the Spherically Symmetric Compressible Navier-Stokes Equations with Density-Dependent Viscosity

Abstract EN

We consider the exterior problem and the initial boundary value problem for the spherically symmetric isentropic compressible Navier-Stokes equations with density-dependent viscosity coefficient in this paper.

For regular initial density, we show that there exists a unique global strong solution to the exterior problem or the initial boundary value problem, respectively.

In particular, the strong solution tends to the equilibrium state as t→+∞.
