Abstract：This paper systematically studies the transverse-only vortex-induced vibration of a circular cylinder with different additional rectifiers. The response amplitude, force coefficient, vibration frequency and vortex shedding mode of a circular cylinder with different additional rectifiers are analyzed at 3.0≤U_r≤12.0. The results show that the hydrodynamic characteristics of the circular cylinder with different additional rectifiers are more complicated than fixed cylinder with additional rectifier. It is not good to evaluate the performance of a rectifier based on the results of a fixed circular cylinder with additional rectifiers.
