N2 - VIV (Vortex induced vibration) is a common fluid-structure interaction phenomenon,which especially occurs in the fields of Marine Engineering. VIV is an important causes of structural fatigue damage. Passive Turbulence Control (PTC) in the form of traveling wave structure (TWS) is used to suppress Flow Induced Motion (FIM) of the circular cylinder in a steady flow. In this paper, the traveling wave structure is fixed on the surface of circular cylinder. Therefore, no additional energy input is required. Firstly, the parameters of the TWS is defined. Secondly, the equation of motion with single degree of freedom is solved using Newmark-β method and compiling UDF for the CFD calculation. The vibration process of cylinder is simulated using the dynamic mesh technique. Finally, the VIV response of circular cylinder with different surfaces are analyzed and summarized. The results of the study can provide references for the VIV suppression of cylinder or tubular structures.
