WebTo accurately simulate flight, the airflow in a wind tunnel must be smooth. Wind tunnels must also be free of the effects of turbulent or unsmooth airflow, which can be caused by forcing the air around the tunnel circuit. Devices such as turning vanes, screens, and slots in tunnel walls help to maintain smooth airflow.
