| Research Abstract |
Experiments were made in an air chamber using a towing paraboloidal-nose or hemi-sphere nose model at high angles of attack. PIV recordings were obtained in planes both perpendicular to and parallel to the body axis to study detailed structure of the vortices in the cross-sections. It was confirmed by the PIV study that equally spaced vortex tubes forming vortex loops around the main vortex, and the corresponding structure was found by flow visualization using titaniumtetrachloride (TiCl4).
