英文摘要: Abstract(#br)Previous studies proved that the triangular prism would go into galloping branch with high amplitude and low frequency. In order to evaluate the energy conversion capacity, a series experiments of flow induced motion (FIM) for triangular prism with physical springs are conducted in the Reynolds number range of 29,559 ≤ Re ≤ 119,376 by varying load resistance, stiffness, mass ratio and aspect ratio. Selective aspect ratios are applied to enhance the hydrokinetic energy captured by the generator. A physical model is used to control the change of load resistance and spring stiffness for a fast and precise oscillator modeling. The analysis of oscillation responses and energy conversion are carried out based on the statistical evaluation of displacement time-history and voltage...
