Abstract: The tidal current turbine is kernel equipment of the tidal current energy conversion(TCEC) device,with its hydrodynamic performance and loads being the basis of the overall and structural design of the TCEC device. So far, the effects of some nonlinear factors, such as flow separation, fluid-structure interaction, vacuoles and complex environmental conditions, on the turbine hydrodynamic performance are still worth further research.Based on the academic achievements in the field of tidal current energy technology obtained by the Harbin Engineering University, review and comparative analysis are conducted on the numerical methods and corresponding results in uniform flow hydrodynamic analysis and fluid-structure interaction analysis of tidal current turbine. Finally, a numerical model is presented on the wave loads of turbines.
