الدراسة النظرية لأهم العوامل المؤثرة في أداء ريشة دوار توربين الرياح

الملخص EN

To date, airfoils with wind turbine rotor blades have been developed for use in aircraft wings.

This is justified when the flow velocity, in the near and far-off zone, which is an aerodynamically important matter, is considered to correspond to the flight velocity.

Even though the requirements of blade airfoil are not exactly the same as the aircraft design requirements.

The wind turbine blade consists of a wide range of elements which can be represented airfoils.

Rotor wind turbine maximum energy required can be achieved through appropriate choice of the form of airfoil which is used to extract dynamic energy of the wind and converted into useful mechanical energy by their shape and position in blade.

The theoretical study airfoils accurately and the criteria for selecting the appropriate form in addition to the study of factors affecting the performance of aerodynamic airfoil on blade rotor wind turbine in order to produce wind turbine can extract the largest amount of wind power less total cost of the system (ideal wind turbine) where the performance of rotor wind turbine depends directly on the aero properties of the airfoils used in the design of the blade.

This required extensive research on the sources of airfoils data and aero characteristics in some universities, libraries competent bulletins and programs for airfoil.

Justifications of this research immenate from the growing global interest in environmental problems, which consider renewable energies as one of the solutions.
