报告摘要:报告摘要:In this talk, I first review briefly the classical Prandtl boundary layer asymptotic expansions in the study of structure of fluids with the high Reynolds number in a domain with boundaries. The vanishing viscosity limit can be regarded as a direct application of Prandtl boundary layer expansions. Next, we consider the related vanishing viscosity limit for 2D compressible viscoelastic Equations and related models with the no-slip boundary conditions on velocity. Compared with the corresponding problem of 2D compressible Navier-Stokes Equations, it shows that the deformation matrix can prevent the strong boundary from occurring.
