Abstract: This paper presents some results from a numerical model for simulating the effect on wave propagation by a controlled vibrating cylinder. The volume of fluid (VOF) technique coupled with the incompressible Navier-Stokes equations and RNG k-ε turbulence closure model are used in the numerical model. The model is first validated by comparing the computed results with those from potential theory for the case of wave diffraction around a stationary cylinder. The two sets of results are in good agreement with each other. The cylinder is then set into oscillation in the same frequency of the incoming wave, but at different phase angles. The free surface profiles near the cylinder vibrating at different phase angles are computed. The results demonstrate that the proposed model is capable of simulating unsteady free surface flows with strong nonlinear fluid-structure interactions.
