Vortex-induced vibration of stay cable under profile velocity using CFD numerical simulation method

Wenli CHEN, Hui LI,

Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 4, Pages 357-363 doi: 10.1007/s11709-009-0060-z

Abstract: Vortex-induced vibration (VIV) of a stay cable subjected to a wind profile is numerically simulated throughA stay cable with the inclined angle of 30° is used as the numerical model.Under a profile of mean wind speed, unsteady aerodynamic lift coefficients of the cable have been analyzedThe results indicate that the lift coefficient wave response of the stay cable under a wind profile isnear the cable and affect the vortex shedding in the wake.
