Highlights Modelling of a deformable pitching flat plate by a two-way implicit FSI approach. Validation of the hydrodynamic part with experimental data. Influence of the flexibility over the structure performances and the hydrodynamic. Drag and lift were enhanced while thrust drops with the flexibility of the plate.
Abstract This study presents a numerical investigation of a 2D flexible flat plate dynamics, immersed in a fluid flow with a Reynolds number, based on its chord, of 2000. The plate is animated by a forced sinusoidal pitching movement, whose amplitude is from its leading edge. Various materials are considered for the structure, from rigid materials to more flexible ones. The Fluid-Structure Interaction (FSI) effects are taken into account using a partitioned implicit coupling scheme. The Arbitrary Lagrangian-Eulerian (ALE) formulation of the Navier-Stokes equations is applied and the anisotropic diffusion equation is solved to determine the displacements of the fluid domain mesh. The numerical results are validated with experimental ones. A good agreement with the experimental results is obtained. Afterwards, it is shown that under the considered dynamics of the plate, the flexibility of the structure tends to increase the lift and the drag but decrease the thrust. In addition, this produces an acceleration of the fluid flow in the wake of the plate.
