Advection in chaotically time-dependent open flows [PDF]

open access: yes, 1998
The passive advection of tracer panicles is considered in open two-dimensional incompressible flows with chaotic time dependence. As illustrative examples we investigate flows produced by chaotically moving ideal point vortices. The advection problem can
