The active power increases with an increasing Reynolds number within the upper branch.
The results show that the Reynolds number affects both amplitude and global response characteristics.
The amplitude, frequency, fluid force, spectral content, active power, and upper limit of power output are analyzed. The V B is varied from 0 V to 165 V, corresponding to 0.082 ≤ ζ total ≤ 1.153. The system total damping ratio ( ζ total) is adjusted by varying excitation voltages ( V B) with a controllable magnetic damping system. Experiments are conducted in six Reynolds number ranges (2.89 × 10 4~6.51 × 10 4 < Re < 7.71 × 10 4~15.21 × 10 4) in regimes of TrSL2, TrS元 and TrBL0. The present study aims to systematically investigate the effects of a high Reynolds number on the flow-induced motion and energy conversion of the Cir-T-Att oscillator.
