TL;DR: In this paper, a time-domain nonlinear numerical model is presented for describing the dynamic stability of point absorbers, where pressure of the incident wave is integrated over the instantaneous wetted surface to obtain the nonlinear Froude-Krylov excitation force and the non linear hydrostatic restoring forces, while first order diffraction-radiation forces are computed by a linear potential flow formulation.

TL;DR: In this article, a CFD methodology involving structure motion and dynamic re-meshing has been optimized and applied to simulate the unsteady flow through normal triangular cylinder arrays with one single tube undergoing either forced oscillations or self-excited oscillations due to damping-controlled fluidelastic instability.

TL;DR: In this article, the fluidelastic behavior of two normal triangular tube arrays subject to cross flow has been tested and a novel feature of the test facility is an electromagnetic device which has been used to control the system damping and to provide additional excitation.

TL;DR: In this article, a two-dimensional wind turbine blade section was simulated using unsteady RANS with the SST turbulence model at Re = 10 6 and high angles of attack.

TL;DR: In this article, an empirical investigation of the acoustically coupled flow field around two tandem cylinders under two different resonant conditions is presented, where the resonant acoustic field could be decoupled from the hydrodynamic flow field, resolved separately, and then recoupled to predict the flow/sound interaction mechanisms using Howe's theory of aerodynamic sound.
