摘要：
This paper presents a study of the movement and the hydrodynamic performance of a new tide-powered hydraulic turbine through numerical simulations. By means of the moving mesh method, the open-closed sequences of the blades and the movement of the rotors are obtained and the angular velocity and the average energy utilization coefficient under different tip speed ratios are also obtained. Moreover, the optimum tip speed ratio is identified by integrating the output power and the energy utilization coefficient of the hydraulic turbine with different tip speed ratios, providing data support for the prototype design of the hydraulic turbine.
