Supersonic conical separation due to shock vorticity

A numerical study of the conical, supersonic, inviscid flow about circular slender cones at large incidence is presented. Although the flow is assumed inviscid, separation and an accompanying spiral are found. This phenomenon is shown to be a valid solution to Euler's equations, i.e., valid in the sense of being independent of any numerical viscosity. The separation and spiral are caused solely by the vorticity produced by a cross-flow shock. The resulting separated flowfields are compared to full potential calculations and to experimental data.
