Extract

A Phenomenon of interest in the study of high-speed aerodynamics concerns the flows generated around very slender bodies of revolution. It has been observed that these bodies, at moderate and large angles of attack, produce a kind of flow pattern that differs considerably from the ones assumed in perfect-fluid treatment according to the usual slender-body analysis.

Photographs reveal that the flow above the upper surface of the body contains two symmetrically disposed spiral vortex sheets which roll up and are carried down-stream. Viewed in respect to the stationary body, the shed vortices appear fixed. The vortices increase in strength as anybody cross plane moves rearward, being eventually discharged to form a Karman vortex street as viewed in the moving cross plane.
