Abstract The change of the side ratio(D/B) for a rectangular cross cylinder will lead to the variation of the surrounding flow field, affecting the aerodynamic performance and vortex-induced vibration(VIV) response on the cylinder. Based on the Fluent platform, the effects of side ratio on vortex-induced vibration of a two-dimensional rectangular cross cylinder with Reynolds number 22000 were studied in combination with the overset grid technology and the fourth-order Runge-Kutta method. Firstly, a rectangular section with a side ratio of D/B=4.0 was selected, and the effectiveness of the simulation method and parameter settings was verified by comparing with the calculated results and relevant literature tests and simulations. Then, the effects of the side ratio on the response of VIV for the rectangular cross cylinder are compared and analyzed from the statistical values of aerodynamic force coefficients, the self-spectrum and the amplitude changes for the flow and transverse direction, and the phase transition. Finally, the influence of different reduced velocity on the wake vortex shedding was analyzed from the respect of transient flow field. The results show that, when the section area of the cross cylinder fixed, the response of VIV for the cylinder with a small side ratio is very weak, and the aerodynamic performance is significantly lower than that of the cylinder with a large side ratio. The aerodynamic performance and VIV response on the cylinder with a large side ratio are higher than that of the standard square cylinder. The amplitude ratio of the cylinder will also change abruptly at a lower reduced velocity, but will reach the peak amplitude at a higher reduced velocity. Compared with the cylindrical structure, the vortex shedding mode of the rectangular cylinder with fixed separation angle is not sensitive to the change of the reduced velocity, which is more obvious on the large side ratio rectangular cylinder than the square cylinder.
