英文摘要：

Based on model experiments in the towing tank in Zhejiang Ocean University, hydrodynamic performance of vertical-axis tidal-current turbine is investigated. Energy efficiency index of the turbine is discussed under different conditions of rotating speeds and flow velocities. Influence of tip-speed ratio, preset angle of airfoil attack and solidity of turbine on the energy efficiency index is analyzed. Effect of waves on the energy efficiency index is investigated. Experimental results may provide technical support for relevant researches.
