英文摘要：

Aiming at the hydrodynamic performance of vertical-axis tidal-current turbine, the model experiment was investigated in towing pool. The testing technique of hydrodynamic performance for the vertical axis tidal-current turbine array was studied, the energy efficiency index of double turbine system was discussed under the condition with the given rotating speed and flow rate. The influence of the axle base distance and the angle between axial line and incoming flow on the energy efficiency index was analyzed by changing the relative position of two turbine models.
