Abstract
The behavior of synchronization in an open flow dynamical system, espe cially in an excited wake flow behind a 2-D oscillating circular cylin der with Reynolds number Re ranging from 45 to 200 is presented. The e xperiment reveals that only under certain conditions can the competiti on between frequencies of oscillating cylinder and the vortex shedding in the wake flow result in ''window of chaos'' with the mixed RTN and Feigenbaum scenario in the range of Re<185.
