| Abstract: | Based on stream tube concept, the paper first analyzed maximum power factor of ideal wind turbine＇s power output while ignoring the rotation of wind turbine blades and other issues. Thereafter, based on the conservation of angular momentum, the power output of wind turbine and maximum power factor considering the rotation of wind turbine blades and resulting rotational wakes are analyzed. Finally, based on the lift concept occurring of airfoil and blade element theory, aerodynamics on vertical shaft turbine blades are analyzed, and the difference between the analysis of aerodynamics on turbine blades and that on airfoil has been pointed out. |
| Keywords: | wind energy conversion vertical shaft wind turbine aerodynamics |
