“…It has been recognized that flapping wings' performance may be inferred from the wake structure of the wings, which exhibits in the case of thrust production jet-like average velocity profiles, associated with a reversed Kármán vortex street [2]. Applying for instance the integral momentum theory to a control volume in which the oscillating body is embedded, the generated thrust can be predicted by velocity measurements in the wake [3,4], the reliability of this approach having been recently addressed in [5,6], comparing measurements with numerical simulation results. Theoretical models for thrust prediction based on potential flow theory have been proposed since the seminal work by Garrick [7], for swimming plates in [8] and more recently for example in [9,10].…”

“…In order to develop a full heaving and pitching deformable hydrofoil model with the consideration of heaving and pitching motions, a preliminary model was implemented and validated. This focused on the modeling of a pitching deformable plate [40]. The same approach is employed in this study to model the pitching motion of the hydrofoil.…”

“…Regarding the solid's domain discretization, the same mesh size used in [40] is employed in this paper (Figure 4b). This mesh density is considered as sufficient because smaller deformations are expected compared to those obtained in [40]. Indeed, the width-tolength ratio of the NACA0015 hydrofoil is twice as large as the one of the plate.…”

The paper focuses on the study of a semi-activated system, based on a combination of two movements of forced pitching and free-heaving motion. Therefore, quantifying with accuracy the hydrodynamic forces applied on the hydrofoil seems to be crucial. This is investigated throughout a numerical analysis of the hydrofoil dynamics. The deformable structure is oscillating in a low-Reynolds number flow. In this study, a hydrofoil animated by a combined forced pitching and heaving movements is considered. Various materials of the hydrofoil structure are studied, from the rigid material to a more flexible one. A partitioned implicit coupling approach is applied in order to consider the Fluid-Structure Interaction (FSI) effects, while the Navier–Stokes equations are solved using the Arbitrary Lagrangian–Eulerian (ALE) method. Both the viscous incompressible Navier–Stokes equations and the elasticity equation are solved using finite volume method. The study is based on the analysis of the hydrodynamic loads acting on the structure. Therefore, the induced dynamics and the power coefficient of the structure are investigated. It is shown that the flexibility of the hydrofoil has an effect on its hydrodynamic behavior. Indeed it increases the load fluctuations and the horizontal mean force component. Furthermore, the unsteady vortices around the hydrofoil are highly impacted by its deformations. Finally, the structure deformations mostly improve the device energy efficiency.
