Journal ArticleDOI
TL;DR: In this paper, a flow control method is employed to mitigate vortex-induced vibration (VIV) of a circular cylinder by using a suction flow method, and the results indicate clearly that the steady suction-flow control method exhibits excellent control effectiveness and can distinctly suppress the VIV by dramatically reducing the amplitudes of cylinder vibrations, fluctuating pressure coefficients and lift coefficients of the circular cylinder model.
