چکیده انگلیسی
The following experimental observations are made: low and high Reynolds VIV significantly differ. The range of synchronization of the upper branch increases with increase in Reynolds number. Amplitude ratio (A/D) increases with Reynolds number within the upper branch. For high-Reynolds, A/D=1.9 is achieved routinely in spite of high damping. The lower branch disappears, overtaken by extended upper branch. High-Reynolds VIV enters into the 2P domain in the Williamson-Roshko (W-R) map beginning with the initial branch. Hysteresis is not observed in these experiments possibly because parameters remain in the 2P-domain. High Reynolds numbers have a stronger influence than mass ratio on A/D. High-damping high-Reynolds VIV amplitudes are double of those predicted by the modified Griffin plot by extrapolation.
