• Flow-Induced Wave of a Flexible Circular Ring Rotating in a Confined Fluid (Theoretical Stability Analysis)

抄録

This paper deals with a theoretical stability analysis of flow-induced waves generated on a flexible circular ring rotating in a confined fluid subjeced to swirling fluid flow. In the stability analysis, wave equation and dispersion relation of the waves are obtained by using the equation of motion of the rotating flexible circular ring based on the Kirchhoff-Love's thin-plate theory and the equation of motion of the fluid flow based on Navier-Stokes equations. As a result, the analytical results show that unstable waves occur on the rotating circular ring due to the swirling fluid flow, and clarify the dynamic characteristics of the unstable waves.
