Geometric Modeling of a Rigid Body Motion in Ideal Fluid with Vorticity

In order to study dynamics of a rigid body moving at low Reynolds number in ambient fluid, we take geometric modelling approach of fully coupled body-fluid system, incorporating Boundary Integral Method of Galerkin type for calculating added masses, and Lie group rigid body integrator. Our aim is to explore numerical advantages of such an approach in comparison to the ’standard’ procedures that comprise volume discretization of a fluid domain.
