摘要: Abstract Flow Induced Motions (FIMs) of rigid circular cylinders, and particularly VIV (Vortex Vibrations) galloping, are induced by alternating lift. The VIVACE (VIV for Aquatic Clean Energy) Converter uses single or multiple in tandem, on elastic end-supports, synergistic FIM, to convert MHK energy electricity. Selectively distributed surface roughness is applied enhance FIM increase efficiency. In this paper, two cylinders used tandem with center-to-center spacing 1.57, 2.0 2.57 diameters, harnessing damping ratio 0.00
