# The dynamics of a rigid body in potential flow with circulation

@article{Vankerschaver2010TheDO, title={The dynamics of a rigid body in potential flow with circulation}, author={Joris Vankerschaver and Eva Kanso and Jerrold E. Marsden}, journal={Regular and Chaotic Dynamics}, year={2010}, volume={15}, pages={606-629} }

We consider the motion of a two-dimensional body of arbitrary shape in a planar irrotational, incompressible fluid with a given amount of circulation around the body. We derive the equations of motion for this system by performing symplectic reduction with respect to the group of volume-preserving diffeomorphisms and obtain the relevant Poisson structures after a further Poisson reduction with respect to the group of translations and rotations. In this way, we recover the equations of motion…
