Fluid forces on a flexible circular cylinder in vortex-induced vibrations Conference Paper uri icon


  • In this work fluid forces acting on a flexible circular cylinder in Vortex-Induced Vibrations (VIV) were studied. An experimental campaing was conducted at low mass-damping ratio (m*cilζ = 0.126) covering the entire lock-in region. The dynamic response of the cylinderwas computed using the Particle TrackingVelocimetry technique on the cylinder free end tip. Drag and lift coefficients (CD and CL) were determined using the experimental data from the cylinder response in a spring-massdamping model. Results show that CL is one order of magnitude greater than CD. Strong cylinder oscillations are associated with a flow pattern showing two vortex center lines corresponding mainly at the upper end of the initial region. © Springer International Publishing Switzerland 2016.
