چکیده انگلیسی

The flow around a wind turbine is a set of forces applied by the wind on the blades defined by the most significant parameters from a dimensional analysis detailing the power of wind turbine. This later is criss- crossed by changes of turbulent intensity unlike the Reynolds number (essential parameter and not unique for the transition to turbulent flow). Thus the performance of the wind turbine depends on the specific speed that allows to get the most power coefficient by controlling the speed. So it's studying the aerodynamics of the wind turbine side in a controlled environment without any uncertainties due atmospheric phenomena.The equations of fluid mechanics (Navier-Stokes) allow the aerodynamic analysis of any flow that satisfy the minimum conditions around a wind turbine as well as factors related to the lift and drag airfoil describing geometry of the blade to the same profile as a function of the Reynolds number and the angle of attack formed between the relative flow and the chord of the blade section.
