... and Beams C. Evangelinos and G.E. Karniadakis Brown University Providence, RI, USA Abst ract We investigated the effect of flow state on the amplitude of vibration in three-dimensional flow-structure interactions at low Reynolds number. In particular, we used a parallel spectral element code to study...
