000014015 520__ $$2eng$$aWe present inviscid and viscous simulations of the trajectory of a counterrotating pair of point vortices in the presence of a flat plate centered on the vortex path, at an angle βp with the horizontal. We vary the plate length and the angle βp . In the inviscid case, the observed dynamics are extremely rich. In particular, singularities are observed that correspond to topological discontinuities in the vortex path as a function of βp . In the viscous case, wall vorticity alters the vortex trajectory dramatically. Most notably, the inviscid limit of the viscous flow does not equal the inviscid solution. We are currently planning outdoor experiments to study the effect of possible wall slip on the flow.
