The hydrofoil plays a crucial role in tidal current energy (TCE) devices, such as horizontal-axis turbines (HATs), vertical-axis (VATs), and oscillating hydrofoils. This study delves into the numerical investigation of passive chordwise spanwise deformations hydrodynamic performance deformable hydrofoil. Three-dimensional (3D) coupled fluid–structure interaction (FSI) simulations were conducted using ANSYS Workbench platform, integrating computational fluid dynamics (CFD) finite element analysis (FEA). simulation involved undergoing pitching motion with varying elastic moduli. scrutinizes impact modulus on deformation, pressure distribution, flow structure, performance. Coefficients lift, drag, torque, well their hysteresis areas intensities, defined to assess correlation between distribution deformation elucidates FSI mechanism. Additionally, investigated 3D effects based structure around Discrepancies along direction result from these effects. Consequently, different cross-sections observed, contributing deformation. difference upper lower surfaces diminished increasing Peak values fluctuations torque decreased. provides insights for selecting an appropriate hydrofoils used TCE devices.
