Turbulent airflow is when the fluid streamlines break into eddies and complex changing patterns. This can cause unstable forces on an object. As the airflow moves from the front of the car to the rear it becomes turbulent. Turning Vane: Deflectors located between the front wheels and sidepods to direct turbulent flow away from the tunnels. This eliminates a source of turbulent air to the tunnels. Cleaner air to the tunnels creates more downforce. Currently seen on most F-1 race cars, and on some Indy Cars.
A type of flow regime characterized by the rapid movement of fluid particles in many direction as welt as the general direction of the overall fluid flow.
A flow field that cannot be described with streamlines in the absolute sense. However, time-averaged streamlines can be defined to describe the average behavior of the flow. In turbulent flow, the inertia stresses dominate over the viscous stresses, leading to small-scale chaotic behavior in the fluid motion.
