摘要：
Vortices exist in wedge-shaped corners in Stokes flow. In seeking an analogous eigensolution structure in three dimensions, an analytic construction is derived for a rectangular corner. This restriction mirrors the only corner type for which computed streamlines are available for comparison and explanation. The dominant eigenvalue is complex, giving rise to localized eddies. Hence trapped fluid is predicted near the corner.
