摘要：
A numerical method using two-way coupling between fluid and structure was presented for simulating the vortex-induced vibration of four cylinders with rectangular arrangement and five cylinders with staggered arrangement in uniform currents. Different spacing ratios L/D in flow direction and space ratio H/D in transverse direction was designed to analyze the influence of rectangular arrangement and staggered arrangement on harvesting energy and power density from currents making advantage of vortex-induced vibration. The results reveal that harvesting energy and amplitude response tend to be stable when combination spacing ratio LH/D2 increased to a certain value. At three different reduced speeds, power density reaches a maximum value when four cylinder system at L/D=2.5, H/D=2 and five cylinder system at L/D=6, H/D=4. According to the results of amplitude response, harvesting energy and power density in different combination space ratio, if more energy is extracted from water currents, the staggered arrangement is better than the rectangular arrangement for a multi-cylinder system.
