Abstract
The influence of solidity and aspect ratio on power coefficient of H-type vertical axis wind turbine,and the change of attack angle with tip speed ratio were analyzed.The results showed that the maximal power coefficient of finite aspect ratio airfoil with aspect ratio equal to 15 was 88.0% of infinite aspect ratio airfoil,and the maximal power coefficient was higher with solidity in 0.1~0.3.
