Certain problems of fluid flow near the core of a spiral discontinuity
Abstract
The structure of the core of a vortex sheet is analyzed in flows that are only slightly different from self-similar ones; on a low-aspect-ratio delta wing this corresponds to a slight curvature of the vortex-sheet axis. Also investigated is the structure of the core of a vortex sheet and a free boundary in axisymmetric self-similar flows. A comparison is made with the two-dimensional case.
