Application of Ultrasonic Velocity Profiler (UVP) in the Vortex-induced Vibration Experiments

An ultrasonic velocity profiler, UVP was used to study the flow properties in the near wake of the rigid and flexible protruding surface. Experiments were conducted in a water tunnel. The performance of turbulence enhancement depends heavily on the motion of the cylinder. An organized oscillating motion is in favor of a higher performance of turbulence enhancement. This research work has provided useful insights of the turbulence characteristics of flow around the fully three-dimensional flexible cantilever, in which the combination of two or three UVP probes are capable in measuring three velocity components.
