Abstract
The characteristic of interaction between flowing air and wind turbine blade is the foundation in the wind turbine blade design and has been a difficult problem in the wind power generation.For a long time,taking the air flow field of wind turbine blades as the objective and on the basis of momentum-blade element theory,the Schmitz method,Glauert method,Wilson method and CFD method have been established to optimize the balde design.However,still a lot of problems need further improvement and study in view of the characteristics of the effect of air on blades during the air flowing through blades.Therefore,the analytical formula of energy transferred from annular flowing air to rotor was proposed based on Bernoulli equation,the analytical formula of torque on the rotor under the annular flow situation was put forward with the principle of momentum,and the analytical formula of transmission power from annular flowing air to rotor was presented.It is obtained that the transmission power is equal to the continuous product of annular air flow,air density,convected velocity of rotor at rim and the projection of the absolute velocity of the air outflowing around the rim.It provides guide for setting trailing edge feature parameters of blade profile curve.关键词
