Example: In the design of an airplane, CFD is used to simulate airflow over the wings to understand how the air moves at different speeds and angles. By adjusting the wing design, engineers can ensure that the aircraft operates with minimal drag and maximum lift, which improves fuel efficiency and performance. CFD helps predict airflow without the need for expensive wind tunnel testing.
