Abstract ： A stationary vortex phenomenon above a nondelta low-aspect-ratio wing was obtained in three-dimensional unsteady numerical simulation. Flow visualization is conducted in water-channel using hydrogen bubbles. The results verify that there is a vortex trapped above the low-aspect-ratio wing and the stationary vortex is consisted of two semi-balls and anti-rotation vortices which are different from the leading edge vortices on the delta wing.
