The reduction of noise and vibration are very important in the design of hydrofoils. The current study focuses on establishing a theoretical and numerical model to investigate fluid-structure interaction caused by elastic hydrofoils in a pulsating flow. A fully coupled three dimensional boundary element method (BEM) and finite element method (FEM) code is applied to analyze the hydrodynamic performance. The numerical results show that the peak frequencies of the support reactions are related to the natural frequency of the hydrofoil. The natural frequencies and support reaction amplitudes are reduced significantly by including the fluid-structure coupling.
