Resumen
Flow-induced vibrations of a flexible cantilever plate, placed in various positions behind two side-by-side cylinders, were computationally investigated to determine optimal location for wake-excited energy harvesters. In the present study, the cylinders of equal diameter D were fixed at center-to-center gap ratio of T/D=1.7" role="presentation">??/??=1.7T/D=1.7

A three-dimensional Navier?Stokes flow solver in an Arbitrary Lagrangian?Eulerian (ALE) description was closely coupled to a non-linear finite element structural solver that was used to model the dynamics of a composite piezoelectric plate.
