AbstractIn suppressing vortex-induced vibration (VIV) of flexible risers in deep sea, a new device based on the Bernoulli equation and effects of geometric disturbance on flows around a bluff body is proposed. The mechanism is the disturbance in a radial-spanwise plane on fluid flows around the body and spanwise uniformity of vortex shedding. In present experiments, two types of disturbance, harmony and cone-like, and different waviness (ratio of wave height to wavelength) of 0.025, 0.05 and 0.1 are investigated. Experimental results have shown that oscillating amplitudes with such disturbance are reduced at mild and high waviness at occurrence of synchronization of a circular cylinder without disturbance. Reduction of RMS values reach up to 48.5% for harmonic disturbance and 53% for cone-like disturbance at the waviness of 0.1.
