N2 - The tidal stream kinetic energy can be abstracted by the horizontal axial turbine, and most concentrate closing to seaside, where the tidal stream turbine must work near the free surface. The interaction between wave surface and the turbine will affect the turbine performance. In this work, the performance of tidal stream turbine working beneath the free surface was simulated, and the wave was discussed. The results indicated that the turbine depth Fr number is the main factor that affects wave induced by the turbine. As the turbine depth Fr number is less than 1.0, the wave is not apparent, and as the Fr number increased, the wave height rose. By the analysis of turbine performance, it is discovered that the wave will influence turbine efficiency, but the relationship between wave height and turbine efficiency is not regular.
