Abstract: Flow-Induced Motion (FIM) phenomena of spring-mounted oscillators were numerically investigated with 2-dimensional simulations to examine the effects of cross section on hydrokinetic energy harnessing. In the simulations, the test flow speed increases from 0.2 m/s to 3.0 m/s (1.61×104 9.6 × 104, the amplitude approaches zero, which means the frequency lock-in phenomenon disappears and the response no longer belongs to VIV or galloping.
