This thesis consists of two parts. Part I is dedicated to understanding the dynamics of a macroscopic particle in a vortical flow. Studies of particle motion in vortical flows have mainly focused on pointlike particles. The aim is to go beyond this approximation and explore the dynamics of an extended object that can experience the nonlinear...

Studies of particle motion in vortical flows have mainly focused on pointlike particles. This approximation assumes that the velocity field that surrounds the particle is linear. We consider an inertialess rigid dumbbell in a two-dimensional steady vortex. While the system remains analytically tractable, the particle experiences the...
