文摘

Free vibrations of a neutrally buoyant cylinder at low damping. Transition from the initial branch (2S mode) and the upper branch (2PO mode). Distinction between the 2S and 2PO modes in terms of length- and velocity-scales. Quantitative characterization of near-wake flow statistics for the 2S and 2PO modes.
