TITLE Corner singularity and regularity for compressible Navier-Stokes flows on polygonal domains: jump discontinuity, grazing corner
ABSTRACT Flows over corners change their behaviors and properties because of an abrupt change in the shape of the corner. Likewise, compressible flows show very singular behaviors over corners. So far the regularity issue is not complete yet. Different BCs yield different corner singularities and, by the transport character for the continuity equation, singularities propagate into the region and generate interior layers and the pressure gradient is not well-defined. I will talk about those issues.
