Audi wind tunnel

In cooperation with Audi AG, Actiflow has developed a boundary layer reduction system for wind tunnels in order to improve the ground simulation. The new control system employs boundary layer suction technology to enable the Audi wind tunnel engineers to control the boundary layer growth on the wind tunnel floor.

This system in addition with a moving belt guarantees a good flow quality at the test section of the wind tunnel. By diminishing effects like flow angularity and pressure gradients, the system improves the correlation between wind tunnel testing and track testing.
