Flap Effect on Trailing Edge of an Airfoil Simulation, ANSYS Fluent Training

In this project, steady airflow over a flapped airfoil with an attack angle equal to 12 degrees is investigated by ANSYS Fluent software. Air velocity magnitude is equal to 45 m/s. The lift coefficient of an airfoil with and without the flap is equal to and , which shows the effectiveness of flap in aerodynamic lift force generation. Moreover, the drag coefficient of the airfoil in the presence of flap is equal to , which is less than airfoil without flap where the drag coefficient is equal to , which proves that flap presence is effective in drag force reduction that is favorable in aerodynamics applications.
