Abstract

A two-dimensional cylinder is subjected to frequency-modulated excitation in the cross-stream direction. Transition from a locked-in response to a completely destabilized response can be attained by lowering the value of modulation frequency while all other parameters are maintained constant. This transition involves progression through a series of identifiable states including lock-in at the modulation frequency, period doubling at the modulation frequency, and spectral-broadened response.
