The are several ways to increase the aerodynamic performance of an airfoil, one of which is adding a section behind the airfoil which commonly called a flap. Flap functions to control aerodynamic performance. The addition of a flap to an airfoil will create a gap beteen the airfoil body and the flap, it will certainly afferct aerodynamic performance.The gap between the flap and the body…
Airfoil is a cross-sectional form that can result in lift force or aerodynamic effects when passing through an airflow. An understanding of crustaristic aerodynamics includes lift efficiency, drag coefficient and Cl/Cd ratio. In this study numerically investigated different types of airfoils to improve the efficiency of wind turbines used in low-speed wind regions. One method of airfo…
