Keywords: leading-edge vortex-breakdown

The behaviors of leading edge vortex and its breakdown, such as vortex core position, the movement of breakdown location, fluctuation, bifurcation and different time scale in the breakdown region as well as surface topology evolution, have been presented. These studies are prerequisites for proper modeling the aerodynamics when vortex breakdown is involved.
