Abstract: As aircraft technology improves, it becomes more important to use the right blade design. Wings can be found on many things, like airplanes, drones, wind machines, and more. ANSYS 2023 Software has been employed for performing a fluent toolbox for CFD analysis upon a NACA 0012 to see what happens to the lift coefficient when the angle of attack is raised. The solver model performed is k-w turbulence simulation was used to look at shape that was made in ANSYS fluent. At a speed of 50m/s, different attack angles between 0° and 25° have been tested to find out the lift and drag coefficients. Raising the angle of attack has been seen to raise the lift coefficient at first, but after a certain angle, the flow separates, and as the angle of attack is raised even more, the lift coefficient begins to decrease. As the turbulence gets stronger, the eddies it creates cause the flow to start breaking away from the airfoil surface. The airfoil's lift coefficient goes down and its drag coefficient goes up at the same time, which makes it perform poorly. The 20° angle of attack has the best performance ratio of 4.53, which means it has the most lift compared to drag of all the angles that were assigned.
