报告摘要：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. This talk is based on a recent work joint with Prof. Tong Yang, Dr. Xinhua Zhao, and Prof. Changjiang Zhu.
