In this paper we present and discuss results from several investigations of the authors and co-workers over the past three years. The studies are primarily directed at the numerical solution of the Euler equations discretized upon a mesh for the case of vortices shed from the leading edge of a delta wing. The speeds in the various cases range from zero to supersonic. The major discussion of the paper points to the use of Computational Fluid Dynamics as a tool for the understanding of the fundamental fluid mechanical processes in this class of flows. Among the issues discussed are the capturing of a vortex sheet upon a mesh, the mechanism of total pressure loss, the stability of the spiral sheet, the structure of a nearly inviscid vortex core, and the stability of the core. The underlying assumption of course is that flow instability can be studied by numerical methods.
