Abstract. In this paper we study Lagrangian transport in the near wake
of a cylinder in the time-periodic regime. We use ideas and methods
from transport theory in dynamical systems to describe and quantify
transport in the near wake. We numerically solve the Navier-Stokes
equations for the velocity field and apply these methods to the
resulting numerical representation of the velocity field. We show that
dynamical systems methods can be used in conjunction with computational
fluid dynamics methods to give very detailed and quantitative
information about Lagrangian transport.
