Upon varying the cylinder spacing, in-phase, in-antiphase and quasi-periodic regimes are observed, by considering the lift and drag forces on the bodies. The relative coefficients vary substantially (in terms of mean and fluctuation rms values) in the range considered, while the Strouhal number is almost constant and near 0.16. The quasi-periodic regime, characterised by a second frequency much lower than the shedding, is studied in most detail. It is shown that the amplitude of the modulation follows a regular pattern in time that can be reproduced by a system of coupled Landau equations.]]> Sat 24 Mar 2018 08:05:14 AEDT ]]>
