|Abstract: ||Abstract:For flows past a cylinder with a transversely oscillatory external forcing, a rapid phase change of π during synchronization has been noted in experimental studies in both laminar and turbulent regimes. In the present analysis, the Stuart–Landau (SL) model that was validated in unforced vortex shedding proves to be a feasible way in predicting this phase change. In addition, using this model other phenomena observed in experimental studies are also noted. These include the possible occurrence of hysteresis, and the broadening of frequency range undergoing phase change with the increase of forcing amplitude|
