Vortex dynamics behind a circular cylinder with a splitter plate in the wake was investigated by the discrete vortex model. The splitter plate was modeled by a series of source which could cancel out the flow across the sources.
The calculation shows that the position of rolling up of elemental vorticies is controlled by both the length of the plate and the gap between the cylinder and the plate. The position is strongly related with the surface flow of the cylinder near the down stream stagnation point.
