Abstract

The problem of calculating nonlinear two-dimensional free-surface potential flow about a pair of counter-rotating point vortices rising under their own influence towards a free surface is solved numerically. The two vortices are inserted into fluid which is initially at rest. A boundary/integral-equation method is used to obtain free-surface elevations and streamlines about the rising pair of vortices for several vortex strengths. The paths of the two vortices are compared with those of a counter-rotating vortex pair under a rigid wall.
