Abstract

One way to increase wind turbine production capacity is to use airfoils with a high coefficient of friction coefficient in wind turbine blades. In airfoils, the coefficient of up and down coefficient depends on the geometry and shape of the airfoil as well as the dependence on the angle of attack and the velocity of wind flow passing through the airfoil. In this study, after introducing important concepts in wind turbines, the E387 airfoil was selected and a new airfoil was designed by modifying and improving the desired airfoil geometry. In the designed airfoil, the ratio of the coefficient of the coefficient to the coefficient of increase was 14.21% compared to the value of the coefficient of initial coefficient, and the highest coefficient of coefficient of coefficient of coefficient of coefficient for the initial coefficient was 124 and 2.5 °. Designed for the new Airfoil, this value is 142 degrees at 4 °, and in the computation and design of the Q-Blade software, which performs simulations using the momentum and correct algorithm models. Modifies the design parameters with the CMDMS model, which uses a two-stage momentum model for aerodynamic simulation of the torque. Inflatable uses, used.
