Tandem cylinders; Mathematical modelling; VIV-galloping interaction
Abstract :
[en] This work focuses on the mathematical modelling of the flow-induced vibrations of tandem cylinders in the post- critical flow. On the basis of experimental aeroelastic tests, the specific case of VIV-galloping interaction is considered. It leads to a model consisting in coupled structural and wake oscillators combined with quasi-steady aerodynamic force coefficients. Static experimental measurements are used as empirical data to develop the mathematical model and identify the values of the different parameters. Aeroelastic experimental tests are intended for validation of the model.
