Abstract :
Renewable energy is an inevitable choice to meet the demands of energy resource. In the 21st century, one of the serious problems facings us is the energy resources that restrict the social progress and sustainable development. Environmental pollution and fossil energy resources shortage force people to explore and use new energy resources. The aim of this paper is to study the effect of blade installation angle on power coef?cient of a ?ve-blade resistance type vertical axis wind turbine using CFD simulations. The computation is conducted for the turbine with the blade diameter of 0.76–0.86 m and the turbine radius R = 2 m. The results show that the maximum value of power ef?ciency of 28.48 % can be obtained when the installation angle is 19 for the ?ve-blade resistance type vertical axis wind turbine with the blade diameter of 0.78 m and the turbine radius R = 2 m.
