title = "Numerical study on aerodynamics and flow physics of a flapping wing hovering in ground effect",
abstract = "The aerodynamics and flow physics of a 3D half-ellipse flat plate flapping wing hovering in ground effect is investigated by computational fluid dynamics method. The flapping motion is dealt with by the overset mesh technology. At the beginning and end of the up-stroke, the impact effect of the jet-flow induced by the small-scale wingtip vortex ring is found for the first time. With the decreasing ground clearance, the averaged forces first decrease and then increase. The ground changes the position and shape of wingtip vortex ring, the attachment ability of bound vortex, and the downwash flow induced by large-scale shedding vortex. And the cause of the fountain effect is further explored in detail.",
