Abstract The determination of the circulation for wind turbine blades is an
important problem in engineering. In the present study, we develop a specific
approach to evaluate the integral that represents mathematically the circulation.
First the potentialities of the method are assessed using a two-dimensional
NACA64_A17 airfoil as a testbed and evaluating the influence of different integration paths and angles of attack on the circulation value. Then the method is
applied to blades with different relative heights in order to provide useful reference data to be used for the optimization and reverse design of wind turbine
blades. As shown by the… More >
