Abstract

Many existing studies show that the ocean tidal turbine experiences frequent and large-scale fluctuations of hydrodynamic loads during its operation, especially when effected by surface waves, which may lead to blade damage due to fatigue. Therefore, the physical wave tank at the University of Galway is referenced and a numerical wave tank model is developed using the commercial Computational Fluid Dynamics (CFD)code ANSYS CFX with calibrated wave parameters from the wave tank as the input wave profile. This numerical wave tank can be combined with a previously developed tidal turbine model to evaluate the hydrodynamic performance of turbines operating in conditions influenced by ocean waves.
