Vortex-induced vibration of a flexible cylinder under bidirectionally sheared flow
ORAL
Abstract
We address the experimental investigation of the vortex-induced vibrations (VIV) of a tensioned flexible cylinder under bidirectionally sheared flow for the first time. The flow field is generated by a verified mechanical apparatus with a diameter of 8.00m. The Fiber Bragg Grating (FBG) strain sensors are applied for the measurement. The modal analysis approach is applied to determine the VIV response. The experiment reveals essential features of flexible cylinder VIV under bidirectionally sheared flow, including root mean square (RMS) VIV amplitudes, low Strouhal numbers and significant traveling wave phenomenon.
