Abstract:
We present the development of an in-house fluid-structure interaction (FSI) solver and employ
the solver for state-of-the-art applications in energy harvesting. An implicit partitioned approach is
utilized to couple a sharp-interface immersed boundary method based flow solver and a finite-element
method based structural solver. The code validations are presented for large-scale flow-induced deformation
and vortex-induced vibration of an elastically mounted circular cylinder. We employ the FSI
solver for analysis of vortex-induced vibration (VIV) of a cylinders, with different cross-sections. The
suppression and agitation of VIV for different cylinders are discussed along with lock-in characteristics.
An energy harvesting model is utilized to estimate the power generated per unit mass and it was found
that the galloping of the D-cylinder is useful for broadband energy harvesting for a wide range of reduced
velocities.
