Investigations are carried out to study the kinematics of a Lagrangian fluid particle due to interaction of an inviscid vortex system. The vortex system considers three inviscid and fixed vortex filaments in various configurations. Effect of external translation and pulsation has been studied on the vortex field to identify the vortex configuration and the nature of external motion which gives rise to maximum enhancement in particle mixing. The non-linear dynamical system governing kinematics of the Lagrangian fluid particle for various vortex configurations has been analyzed using Poincare maps, autocorrelation and Lyapunov exponents with an aim to find possible chaotic particle trajectories. Fixed points of the dynamical system associated with poor transport properties have been identified.
