By using the software ANSYS Fluent, this paper developed a numerical wave tank based on Stokes fifth-order wave theory and artificial damping absorber. Two-way coupling between waves and a finite submerged flexible short plate is simulated in the numerical wave tank, and the plate is modeled by finite elements. Hydroelectric vibration of the plate and transmission of incident surface waves over the plate are analyzed with various flexural stiffness and submerged depth. The simulations show a complex dynamic coupling between the plate and waves, and wave-structure resonance is clearly observed. Resonance happens under a specific combination of wave length, stiffness and depth. The two-way wave-structure coupled platform developed in the paper has been demonstrated to accurately simulate interaction between a short flexible submerged plate and waves, providing a reliable research tool for fluid-structure interaction studies.
