内容摘要：

We consider the vanishing shear viscosity limit of the initial boundary value problem for the isentropic compressible Navier-Stokes equations with cylindrical symmetry. By using the matched asymptotic expansion, we derive explicit Prandtl type boundary layer equations. Moreover, we prove the global-in-time stability of the boundary layer profile together with the optimal convergence rate of the vanishing shear viscosity limit without any smallness assumption on the initial and boundary data.
