Based on Lattice Boltzmann Method, a free interface tracking model using volume of fraction (VOF) technique is built to explore the interaction of Oscillating Water Column (OWC) type of Wave Energy Converters (WECs) with waves. In the numerical wave flume, the momentum source is applied to generate incident waves and absorb reflected waves. After validation, one stationary OWC in the absence of Power take-off system (PTO) is then placed in the numerical wave flume to examine the performance of the numerical scheme. The simulation results show that the numerical stability is well achieved with the wave-structure interaction included and there is a strong vortex shedding at wall corner and nonlinearity with smaller amplitude in the present viscous flow model, compared with the linear potential flow solution.
