Zl. Wei et al., ORDERED AND CHAOTIC PHENOMENA OF VORTEX SHEDDING IN AN EXCITED WAKE FLOW BEHIND A 2-D OSCILLATING CIRCULAR-CYLINDER, Science in China. Series A, Mathematics, Physics, Astronomy & Technological Sciences, 38(4), 1995, pp. 447-461
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.
