Smoke Tunnel Experiment on Aeroplane Wing

Image
How can we see the airflow over the wings of an aeroplane? We can make a small model or replica of the aeroplane wing and see the airflow past it inside the smoke tunnel. As the angle of attack changes, we can see interesting changes occurring to the flow streamlines. Few of the streamlines which were going below the wing at low angle of attack, change their direction and start going above the wing at higher angle of attack.
