• The vortices shed behind a 15%-thick, two-dimensional elliptic cylinder rotating around its spanwise axis perpendicularly to a uniform flow were numerically analyzed using discrete vortex-blob method. The color coded vorticity distributions in the flow field were displayed in both cases of the forced and autorotation. Moreover, a 16 mm animation movie of it was made to visualize vortex interactions. By means of this color graphic simulation, the merging rearrangement, interaction and splitting of the vortices in the wake flow of a rotating wing were demonstrated making these processes clearly understandalbe.
