Abstract

In this paper, we study the initial boundary value problem for the three-dimensional spherically symmetric compressible Oldroyd-B system as the diffusion parameter $ \varepsilon $ goes to 0. Explicit Prandtl-type boundary layer equations are derived, and the stability of the boundary layer profile is established.
