The asymmetric vortices can be determined through setting the artificial perturbation on the nose of the blunt body at high angle of attack. To study the influence of perturbation geometry on the asymmetric vortices, numerical simulation was applied and the hemispherical, D-type and square perturbations were set on the position circumferential angle 90° and meridian angle 10° respectively at the angle of attack 50° and
